如何使用 pip 列出所有可用的软件包版本？

发布于 2024-10-15 17:52:16 字数 215 浏览 1 评论 0原文

给定可以使用 pip 安装的 Python 包的名称，有什么方法可以找到列出 pip 可以安装的所有可能版本？现在正在尝试和错误。

我正在尝试安装第三方库的版本，但最新版本太新，做出了向后不兼容的更改。所以我想以某种方式拥有 pip 知道的所有版本的列表，以便我可以测试它们。

原文

Given the name of a Python package that can be installed with pip, is there any way to find out a list of all the possible versions of it that pip could install? Right now it's trial and error.

I'm trying to install a version for a third party library, but the newest version is too new, there were backwards incompatible changes made. So I'd like to somehow have a list of all the versions that pip knows about, so that I can test them.

对于 pip >= 21.2 使用：

pip index versions pylibmc

请注意，此命令是实验性的，将来可能会发生变化！

以下方法与 2024 年 6 月 21 日发布的 pip 24.1 不同。

对于 pip >= 21.1 使用：

pip install pylibmc==

对于 pip >= 20.3 使用：

pip install --use-deprecated=legacy-resolver pylibmc==

对于 pip >= 9.0 使用：

$ pip install pylibmc==
Collecting pylibmc==
  Could not find a version that satisfies the requirement pylibmc== (from 
  versions: 0.2, 0.3, 0.4, 0.5.1, 0.5.2, 0.5.3, 0.5.4, 0.5.5, 0.5, 0.6.1, 0.6, 
  0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.7, 0.8.1, 0.8.2, 0.8, 0.9.1, 0.9.2, 0.9, 
  1.0-alpha, 1.0-beta, 1.0, 1.1.1, 1.1, 1.2.0, 1.2.1, 1.2.2, 1.2.3, 1.3.0)
No matching distribution found for pylibmc==

可用版本为无需实际下载或安装任何软件包即可打印。

对于点 9.0 使用：

pip install pylibmc==blork

其中 blork 可以是任何 不是有效的版本号。

For pip >= 21.2 use:

pip index versions pylibmc

Note that this command is experimental, and might change in the future!

Below approach breaks with pip 24.1 released on 2024-06-21.

For pip >= 21.1 use:

pip install pylibmc==

For pip >= 20.3 use:

pip install --use-deprecated=legacy-resolver pylibmc==

For pip >= 9.0 use:

$ pip install pylibmc==
Collecting pylibmc==
  Could not find a version that satisfies the requirement pylibmc== (from 
  versions: 0.2, 0.3, 0.4, 0.5.1, 0.5.2, 0.5.3, 0.5.4, 0.5.5, 0.5, 0.6.1, 0.6, 
  0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.7, 0.8.1, 0.8.2, 0.8, 0.9.1, 0.9.2, 0.9, 
  1.0-alpha, 1.0-beta, 1.0, 1.1.1, 1.1, 1.2.0, 1.2.1, 1.2.2, 1.2.3, 1.3.0)
No matching distribution found for pylibmc==

The available versions will be printed without actually downloading or installing any packages.

For pip < 9.0 use:

pip install pylibmc==blork

where blork can be any string that is not a valid version number.

（更新：截至 2020 年 3 月，许多人报告通过 pip install yolk3k 安装的 yolk 仅返回最新版本。克里斯的回答似乎得到了最多的支持并且对我有用）

pastebin的脚本确实有效。但是，如果您正在使用多个环境/主机，则不太方便，因为您每次都必须复制/创建它。

更好的全能解决方案是使用 yolk3k，它可以通过 pip 安装。例如，查看可用的 Django 版本：

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k 是原始 的分支yolk 于 2012 停止开发。虽然 yolk 不再维护（如下面的评论所示），但 yolk3k 似乎是并支持 Python 3。

注意： 我不参与在 yolk3k 的开发中。 如果某些东西似乎无法正常工作，在这里留下评论应该不会有太大影响。使用yolk3k 问题跟踪器 相反，并考虑提交修复（如果可能）。

(update: As of March 2020, many people have reported that yolk, installed via pip install yolk3k, only returns latest version. Chris's answer seems to have the most upvotes and worked for me)

The script at pastebin does work. However it's not very convenient if you're working with multiple environments/hosts because you will have to copy/create it every time.

A better all-around solution would be to use yolk3k, which is available to install with pip. E.g. to see what versions of Django are available:

$ pip install yolk3k
$ yolk -V django
Django 1.3
Django 1.2.5
Django 1.2.4
Django 1.2.3
Django 1.2.2
Django 1.2.1
Django 1.2
Django 1.1.4
Django 1.1.3
Django 1.1.2
Django 1.0.4

yolk3k is a fork of the original yolk which ceased development in 2012. Though yolk is no longer maintained (as indicated in comments below), yolk3k appears to be and supports Python 3.

Note: I am not involved in the development of yolk3k. If something doesn't seem to work as it should, leaving a comment here should not make much difference. Use the yolk3k issue tracker instead and consider submitting a fix, if possible.

您不需要第三方包来获取此信息。 pypi 为下面的所有包提供简单的 JSON 源，

https://pypi.org/pypi/{PKG_NAME}/json

这是一些仅使用获取所有版本的标准库的 Python 代码。

import requests
from distutils.version import LooseVersion

def versions(package_name, limit_releases=10):
    url = f"https://pypi.org/pypi/{package_name}/json"
    data = requests.get(url).json()
    versions = list(data["releases"].keys())
    versions.sort(key=LooseVersion, reverse=True)
    return versions[:limit_releases]

print("\n".join(versions("typeguard")))

该代码打印（截至 2023 年 7 月 21 日）：

4.0.0rc6
4.0.0rc5
4.0.0rc4
4.0.0rc3
4.0.0rc2
4.0.0rc1
4.0.0
3.0.2
3.0.1
3.0.0rc2

You don't need a third party package to get this information. pypi provides simple JSON feeds for all packages under

https://pypi.org/pypi/{PKG_NAME}/json

Here's some Python code using only the standard library which gets all versions.

import requests
from distutils.version import LooseVersion

def versions(package_name, limit_releases=10):
    url = f"https://pypi.org/pypi/{package_name}/json"
    data = requests.get(url).json()
    versions = list(data["releases"].keys())
    versions.sort(key=LooseVersion, reverse=True)
    return versions[:limit_releases]

print("\n".join(versions("typeguard")))

That code prints (as of 21/Jul/2023):

4.0.0rc6
4.0.0rc5
4.0.0rc4
4.0.0rc3
4.0.0rc2
4.0.0rc1
4.0.0
3.0.2
3.0.1
3.0.0rc2

我想出了一个极其简单的 bash 脚本。感谢 jq 的作者。

#!/bin/bash
set -e

PACKAGE_JSON_URL="https://pypi.org/pypi/${1}/json"

curl -L -s "$PACKAGE_JSON_URL" \
    | jq  -r '.releases \
    | keys | .[]' \
    | sort -V

更新：

  • 添加按版本号排序。
  • 添加 -L 以遵循重定向。

I came up with dead-simple bash script. Thanks to jq's author.

#!/bin/bash
set -e

PACKAGE_JSON_URL="https://pypi.org/pypi/${1}/json"

curl -L -s "$PACKAGE_JSON_URL" \
    | jq  -r '.releases \
    | keys | .[]' \
    | sort -V

Update:

  • Add sorting by version number.
  • Add -L to follow redirects.

您可以使用这个小型 Python 3 脚本（仅使用标准库模块）使用 JSON API 并按时间倒序打印它们。与此处发布的其他一些 Python 解决方案不同，这不会在 django 的 2.2rc1 或 uwsgi 的 等松散版本上中断。 2.0.17.1：

#!/usr/bin/env python3

import json
import sys
from urllib import request    
from pkg_resources import parse_version    

def versions(pkg_name):
    url = f'https://pypi.python.org/pypi/{pkg_name}/json'
    releases = json.loads(request.urlopen(url).read())['releases']
    return sorted(releases, key=parse_version, reverse=True)    

if __name__ == '__main__':
    print(*versions(sys.argv[1]), sep='\n')

保存脚本并以包名称作为参数运行它，例如：

python versions.py django

3.0a1
2.2.5
2.2.4
2.2.3
2.2.2
2.2.1
2.2
2.2rc1
...

You can use this small Python 3 script (using only standard library modules) to grab the list of available versions for a package from PyPI using JSON API and print them in reverse chronological order. Unlike some other Python solutions posted here, this doesn't break on loose versions like django's 2.2rc1 or uwsgi's 2.0.17.1:

#!/usr/bin/env python3

import json
import sys
from urllib import request    
from pkg_resources import parse_version    

def versions(pkg_name):
    url = f'https://pypi.python.org/pypi/{pkg_name}/json'
    releases = json.loads(request.urlopen(url).read())['releases']
    return sorted(releases, key=parse_version, reverse=True)    

if __name__ == '__main__':
    print(*versions(sys.argv[1]), sep='\n')

Save the script and run it with the package name as an argument, e.g.:

python versions.py django

3.0a1
2.2.5
2.2.4
2.2.3
2.2.2
2.2.1
2.2
2.2rc1

看了一会儿pip的代码，貌似负责定位包的代码可以在pip.index中的PackageFinder类中找到。它的方法 find_requirement 查找 InstallRequirement 的版本，但遗憾的是仅返回最新版本。

下面的代码几乎是原始函数的 1:1 副本，其中第 114 行的 return 更改为返回所有版本。

该脚本需要一个包名称作为第一个也是唯一的参数，并返回所有版本。

我不能保证正确性，因为我不熟悉 pip 的代码。但希望这会有所帮助。

示例输出

    req = InstallRequirement.from_line(sys.argv[1], None)

    versions = finder.find_requirement(req, False)
    print 'Versions of %s' % sys.argv[1]
    for v in versions:
        print v[1]

After looking at pip's code for a while, it looks like the code responsible for locating packages can be found in the PackageFinder class in pip.index. Its method find_requirement looks up the versions of a InstallRequirement, but unfortunately only returns the most recent version.

The code below is almost a 1:1 copy of the original function, with the return in line 114 changed to return all versions.

The script expects one package name as first and only argument and returns all versions.

I can't guarantee for the correctness, as I'm not familiar with pip's code. But hopefully this helps.

Sample output

python test.py pip

你可以用 yolk3k 包代替蛋黄。 yolk3k 是原始 yolk 的一个分支，它支持 python2 和 3。

https://github.com/myint/蛋黄

pip install yolk3k

You could the yolk3k package instead of yolk. yolk3k is a fork from the original yolk and it supports both python2 and 3.

也许不再需要该解决方案，请检查对此答案的评论。

原始答案

对于 20.03 以上的 pip 版本，您可以使用旧的求解器来恢复所有可用版本：

$ pip install  --use-deprecated=legacy-resolver pylibmc==
ERROR: Could not find a version that satisfies the requirement pylibmc== (from

ERROR: No matching distribution found for pylibmc==

Update:

Maybe the solution is not needed anymore, check comments to this answer.

Original Answer

With pip versions above 20.03 you can use the old solver in order to get back all the available versions:

$ pip install  --use-deprecated=legacy-resolver pylibmc==
ERROR: Could not find a version that satisfies the requirement pylibmc== (from

1.9.0rc4
1.9.0
1.10.0rc1

1.10.0

或者获取可用的最新版本：

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n' \
| gsort -r -V \
| head -1

1.10.0rc2

请记住，必须安装（在 OSX 上）gsort 才能解析版本。您可以使用 brew install coreutils 安装它

This works for me on OSX:

pip install docker-compose== 2>&1 \
| grep -oE '(\(.*\))' \
| awk -F:\  '{print$NF}' \
| sed -E 's/( |\))//g' \
| tr ',' '\n'

It returns the list one per line:

Or to get the latest version available:

pip install docker-compose== 2>&1 \

我通常运行pip install packagename==somerandomstring。这会返回错误，指出无法找到满足要求的版本 packagename==somerandomstring 并且除了该错误之外，pip 还将列出服务器上的可用版本。

例如

$ pip install flask==aksjflashd
Collecting flask==aksjflashd
  Could not find a version that satisfies the requirement flask==aksjflashd 
(from versions: 0.1, 0.2, 0.3, 0.3.1, 0.4, 0.5, 0.5.1, 0.5.2, 0.6, 0.6.1, 0.7, 0.7.1, 0.7.2, 0.8, 0.8.1, 0.9, 0.10, 0.10.1, 0.11, 0.11.1, 0.12, 0.12.1, 
0.12.2, 0.12.3, 0.12.4, 0.12.5, 1.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.1.0, 1.1.1, 1.1.2)
No matching distribution found for flask==aksjflashd
$

，如果像“aksjflashd”这样的随机字符串结果是实际的软件包版本，那么您一定非常不幸！

当然，您也可以在 pip download 中使用此技巧。

I usually run pip install packagename==somerandomstring. This returns error saying Could not find a version that satisfies the requirement packagename==somerandomstring and along with that error, pip will also list available versions on the server.

e.g.

$ pip install flask==aksjflashd
Collecting flask==aksjflashd
  Could not find a version that satisfies the requirement flask==aksjflashd 
(from versions: 0.1, 0.2, 0.3, 0.3.1, 0.4, 0.5, 0.5.1, 0.5.2, 0.6, 0.6.1, 0.7, 0.7.1, 0.7.2, 0.8, 0.8.1, 0.9, 0.10, 0.10.1, 0.11, 0.11.1, 0.12, 0.12.1, 
0.12.2, 0.12.3, 0.12.4, 0.12.5, 1.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.1.0, 1.1.1, 1.1.2)
No matching distribution found for flask==aksjflashd
$

You have to be extremely unlucky if the random string like 'aksjflashd' turns out to be actual package version!

Of course, you can use this trick with pip download too.

替代解决方案是使用 Warehouse API：

https://warehouse.readthedocs.io/api -reference/json/#release

例如对于 Flask：

import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())

将打印：

dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])

Alternative solution is to use the Warehouse APIs:

https://warehouse.readthedocs.io/api-reference/json/#release

For instance for Flask:

import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())

will print:

dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])

这是我的答案，它对 jq 内的列表进行排序（对于那些使用 sort -V 不可用的系统的人）：

$ pythonPackage=certifi
$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )'
  ............. 
  "2019.3.9",
  "2019.6.16",
  "2019.9.11",
  "2019.11.28",
  "2020.4.5",
  "2020.4.5.1",
  "2020.4.5.2",
  "2020.6.20",
  "2020.11.8"
]

并获取包的最后版本号：

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )[-1]'
2020.11.8

或更快一点：

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | max_by( split(".") | map(tonumber) )'
2020.11.8

或者更简单：）：

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r .info.version
2020.11.8

Here's my answer that sorts the list inside jq (for those who use systems where sort -V is not avalable) :

$ pythonPackage=certifi
$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )'
  ............. 
  "2019.3.9",
  "2019.6.16",
  "2019.9.11",
  "2019.11.28",
  "2020.4.5",
  "2020.4.5.1",
  "2020.4.5.2",
  "2020.6.20",
  "2020.11.8"
]

And to fetch the last version number of the package :

$ curl -Ls https://pypi.org/pypi/$pythonPackage/json | jq -r '.releases | keys_unsorted | sort_by( split(".") | map(tonumber) )[-1]'

简单的 bash 脚本仅依赖于 python 本身（我假设在问题的上下文中应该安装它）和 curl 或之一wget。它假设您安装了 setuptools 软件包来对版本进行排序（几乎总是安装）。它不依赖于外部依赖项，例如

  • 可能不存在的jq；
  • grep 和 awk 在 Linux 和 macOS 上的行为可能有所不同。
curl --silent --location https://pypi.org/pypi/requests/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))"

带有注释的较长版本。

将包名称放入变量中：

PACKAGE=requests

获取版本（使用 curl）：

VERSIONS=$(curl --silent --location https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

获取版本（使用 wget） ：

VERSIONS=$(wget -qO- https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

打印排序版本：

echo $VERSIONS

Simple bash script that relies only on python itself (I assume that in the context of the question it should be installed) and one of curl or wget. It has an assumption that you have setuptools package installed to sort versions (almost always installed). It doesn't rely on external dependencies such as:

  • jq which may not be present;
  • grep and awk that may behave differently on Linux and macOS.
curl --silent --location https://pypi.org/pypi/requests/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))"

A little bit longer version with comments.

Put the package name into a variable:

PACKAGE=requests

Get versions (using curl):

VERSIONS=$(curl --silent --location https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

Get versions (using wget):

VERSIONS=$(wget -qO- https://pypi.org/pypi/$PACKAGE/json | python -c "import sys, json, pkg_resources; releases = json.load(sys.stdin)['releases']; print(' '.join(sorted(releases, key=pkg_resources.parse_version)))")

Print sorted versions:

echo $VERSIONS

要查找所有可用的（甚至不兼容）版本，请使用 -vv 标志和 pip >= 21.x。

pip install sklearn== --dry-run -vv

不兼容的版本将在日志中列出，如下所示：

Skipping link: none of the wheel's tags (cp27-cp27m-win32) are compatible

To find all available (even incompatible) versions as well, use the -vv flag with pip >= 21.x.

pip install sklearn== --dry-run -vv

Incompatible versions will be listed in the log like this:

Skipping link: none of the wheel's tags (cp27-cp27m-win32) are compatible

在 pip 的更新版本中，以下解决方案不起作用：

请在 == 之后使用任何随机数，而不是这些解决方案，如下所示：

pip install django==121312

要纠正您，终端将显示所有可用版本。您可以选择适合您的版本。

In the updated version of pip the following solution doesn't work:

pip install django==
pip install django==anyrandomstring

我的看法是结合了几个已发布的答案，并进行了一些修改，以使它们更容易在运行的 python 环境中使用。

这个想法是提供一个全新的命令（以 install 命令为模型），为您提供一个要使用的包查找器的实例。优点是它可以与 pip 支持的任何索引配合使用并读取本地 pip 配置文件，因此您可以获得正确的结果，就像正常的 pip 安装一样。

我尝试使其与 pip v 9.x 和 10.x 兼容..但只在 9.x

My take is a combination of a couple of posted answers, with some modifications to make them easier to use from within a running python environment.

The idea is to provide a entirely new command (modeled after the install command) that gives you an instance of the package finder to use. The upside is that it works with, and uses, any indexes that pip supports and reads your local pip configuration files, so you get the correct results as you would with a normal pip install.

I've made an attempt at making it compatible with both pip v 9.x and 10.x.. but only tried it on 9.x

使用 pip install== 为 Chris 的答案 提供编程方法，

import re
import subprocess
from packaging.version import VERSION_PATTERN as _VRESION_PATTERN

VERSION_PATTERN = re.compile(_VRESION_PATTERN , re.VERBOSE | re.IGNORECASE)


def get_available_versions(package_name):
    process = subprocess.run(['pip', 'install', f'{package_name}=='], stdout=subprocess.DEVNULL, stderr=subprocess.PIPE)
    versions = []
    for line in process.stderr.decode('utf-8').splitlines():
        if 'Could not find a version that satisfies the requirement' in line:
            for match in VERSION_PATTERN.finditer(line.split('from versions:')[1]):
                versions.append(match.group(0))
    return versions

可以像这样使用

>>> get_available_versions('tensorflow')
['2.2.0rc1', '2.2.0rc2', '2.2.0rc3', '2.2.0rc4', '2.2.0', '2.2.1', '2.2.2', '2.2.3', '2.3.0rc0', '2.3.0rc1', '2.3.0rc2', '2.3.0', '2.3.1', '2.3.2', '2.3.3', '2.3.4', '2.4.0rc0', '2.4.0rc1', '2.4.0rc2', '2.4.0rc3', '2.4.0rc4', '2.4.0', '2.4.1', '2.4.2', '2.4.3', '2.4.4', '2.5.0rc0', '2.5.0rc1', '2.5.0rc2', '2.5.0rc3', '2.5.0', '2.5.1', '2.5.2', '2.5.3', '2.6.0rc0', '2.6.0rc1', '2.6.0rc2', '2.6.0', '2.6.1', '2.6.2', '2.6.3', '2.7.0rc0', '2.7.0rc1', '2.7.0', '2.7.1', '2.8.0rc0', '2.8.0rc1', '2.8.0']

并返回版本列表。

注意：它似乎提供兼容版本而不是所有版本。要获取完整列表，请使用 Eric 的 json 方法。

Providing a programmatic approach to Chris's answer using pip install <package_name>==

import re
import subprocess
from packaging.version import VERSION_PATTERN as _VRESION_PATTERN

VERSION_PATTERN = re.compile(_VRESION_PATTERN , re.VERBOSE | re.IGNORECASE)


def get_available_versions(package_name):
    process = subprocess.run(['pip', 'install', f'{package_name}=='], stdout=subprocess.DEVNULL, stderr=subprocess.PIPE)
    versions = []
    for line in process.stderr.decode('utf-8').splitlines():
        if 'Could not find a version that satisfies the requirement' in line:
            for match in VERSION_PATTERN.finditer(line.split('from versions:')[1]):
                versions.append(match.group(0))
    return versions

It can be used like

>>> get_available_versions('tensorflow')
['2.2.0rc1', '2.2.0rc2', '2.2.0rc3', '2.2.0rc4', '2.2.0', '2.2.1', '2.2.2', '2.2.3', '2.3.0rc0', '2.3.0rc1', '2.3.0rc2', '2.3.0', '2.3.1', '2.3.2', '2.3.3', '2.3.4', '2.4.0rc0', '2.4.0rc1', '2.4.0rc2', '2.4.0rc3', '2.4.0rc4', '2.4.0', '2.4.1', '2.4.2', '2.4.3', '2.4.4', '2.5.0rc0', '2.5.0rc1', '2.5.0rc2', '2.5.0rc3', '2.5.0', '2.5.1', '2.5.2', '2.5.3', '2.6.0rc0', '2.6.0rc1', '2.6.0rc2', '2.6.0', '2.6.1', '2.6.2', '2.6.3', '2.7.0rc0', '2.7.0rc1', '2.7.0', '2.7.1', '2.8.0rc0', '2.8.0rc1', '2.8.0']

and return a list of versions.

Note: it seems to provide compatible releases rather than all releases. To get full list, use json approach from Eric.
