setup.py 是一个 Python 文件,它的存在表明您要安装的模块/包可能已通过 Distutils,这是分发 Python 模块的标准。

这使您可以轻松地安装 Python 包。通常这样写就足够了:

$ pip install . 

pip将使用setup.py来安装你的模块。避免直接调用 setup.py

setup.py is a Python file, the presence of which is an indication that the module/package you are about to install has likely been packaged and distributed with Distutils, which is the standard for distributing Python Modules.

This allows you to easily install Python packages. Often it's enough to write:

$ pip install . 

pip will use setup.py to install your module. Avoid calling setup.py directly.

它有助于在您的计算机上安装 python 包 foo(也可以在 virtualenv 中),以便您可以从其他项目导入包 foo以及 [I]Python 提示。

它的作用与pipeasy_install等类似,


使用setup.py

让我们从一些定义开始:

- 包含__init__.py 文件的文件夹/目录。
模块 - 具有 .py 扩展名的有效 python 文件。
分发 - 一个如何与其他模块相关。

假设您要安装一个名为 foo 的包。 那么您就可以这样做

$ git clone https://github.com/user/foo
$ cd foo
$ python setup.py install

如果您不想实际安装它但仍想使用它, 。然后执行此命令,

$ python setup.py develop

该命令将在站点包中创建指向源目录的符号链接,而不是复制内容。因此,它的速度相当快(特别是对于大包)。


创建 setup.py

如果您的包树类似于,

foo
├── foo
│   ├── data_struct.py
│   ├── __init__.py
│   └── internals.py
├── README
├── requirements.txt
└── setup.py

那么,您可以在 setup.py 中执行以下操作> 脚本,以便可以将其安装在某些计算机上:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
)

相反,如果您的包树更复杂,如下所示:

foo
├── foo
│   ├── data_struct.py
│   ├── __init__.py
│   └── internals.py
├── README
├── requirements.txt
├── scripts
│   ├── cool
│   └── skype
└── setup.py

那么,在这种情况下,您的 setup.py 将就像:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

向 (setup.py) 添加更多内容 &让它得体:

from setuptools import setup

with open("README", 'r') as f:
    long_description = f.read()

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   license="MIT",
   long_description=long_description,
   author='Man Foo',
   author_email='[email protected]',
   url="http://www.foopackage.example/",
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

long_descriptionpypi.org中用作包的自述文件描述。


最后,您现在已准备好将软件包上传到 PyPi.org,以便其他人可以使用 pip 安装你的包

此时有两个选择。

  • 临时 test.pypi.org 服务器中发布自己熟悉该过程,然后将其发布在永久pypi.org服务器供公众使用您的包。
  • 如果您已经熟悉,请立即在永久 pypi.org 服务器上发布 请按照该过程并获得您的用户凭据(例如,用户名、密码、包名称)

一旦您的包名称在 pypi 中注册, 。 org,没有人可以声明或使用它。 Python 打包建议使用 twine 包< /a> 用于上传(将包上传到 PyPi)。因此,

  1. 第一步是使用以下方法在本地构建发行版:

    # 先决条件:wheel (pip install wheel)
    $ python setup.py sdist bdist_wheel
    
  2. 然后使用twine上传到test.pypi.orgpypi.org

    $ twine upload --repository testpypi dist/*
    用户名:***
    密码: ***
    

包需要几分钟时间才会出现在 <代码>test.pypi.org。一旦您对它感到满意,您就可以将您的包上传到真实的&amp; pypi.org 的永久索引只需:

$ twine upload dist/*

或者,您还可以使用 < 来签署包中的文件code>GPG 作者:

$ twine upload dist/* --sign

额外阅读

It helps to install a python package foo on your machine (can also be in virtualenv) so that you can import the package foo from other projects and also from [I]Python prompts.

It does the similar job of pip, easy_install etc.,


Using setup.py

Let's start with some definitions:

Package - A folder/directory that contains __init__.py file.
Module - A valid python file with .py extension.
Distribution - How one package relates to other packages and modules.

Let's say you want to install a package named foo. Then you do,

$ git clone https://github.com/user/foo
$ cd foo
$ python setup.py install

Instead, if you don't want to actually install it but still would like to use it. Then do,

$ python setup.py develop

This command will create symlinks to the source directory within site-packages instead of copying things. Because of this, it is quite fast (particularly for large packages).


Creating setup.py

If you have your package tree like,

foo
├── foo
│   ├── data_struct.py
│   ├── __init__.py
│   └── internals.py
├── README
├── requirements.txt
└── setup.py

Then, you do the following in your setup.py script so that it can be installed on some machine:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
)

Instead, if your package tree is more complex like the one below:

foo
├── foo
│   ├── data_struct.py
│   ├── __init__.py
│   └── internals.py
├── README
├── requirements.txt
├── scripts
│   ├── cool
│   └── skype
└── setup.py

Then, your setup.py in this case would be like:

from setuptools import setup

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   author='Man Foo',
   author_email='[email protected]',
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

Add more stuff to (setup.py) & make it decent:

from setuptools import setup

with open("README", 'r') as f:
    long_description = f.read()

setup(
   name='foo',
   version='1.0',
   description='A useful module',
   license="MIT",
   long_description=long_description,
   author='Man Foo',
   author_email='[email protected]',
   url="http://www.foopackage.example/",
   packages=['foo'],  #same as name
   install_requires=['wheel', 'bar', 'greek'], #external packages as dependencies
   scripts=[
            'scripts/cool',
            'scripts/skype',
           ]
)

The long_description is used in pypi.org as the README description of your package.


And finally, you're now ready to upload your package to PyPi.org so that others can install your package using pip install yourpackage.

At this point there are two options.

  • publish in the temporary test.pypi.org server to make oneself familiarize with the procedure, and then publish it on the permanent pypi.org server for the public to use your package.
  • publish straight away on the permanent pypi.org server, if you are already familiar with the procedure and have your user credentials (e.g., username, password, package name)

Once your package name is registered in pypi.org, nobody can claim or use it. Python packaging suggests the twine package for uploading purposes (of your package to PyPi). Thus,

  1. the first step is to locally build the distributions using:

    # prereq: wheel (pip install wheel)
    $ python setup.py sdist bdist_wheel
    
  2. then using twine for uploading either to test.pypi.org or pypi.org:

    $ twine upload --repository testpypi dist/*
    username: ***
    password: ***
    

It will take few minutes for the package to appear on test.pypi.org. Once you're satisfied with it, you can then upload your package to the real & permanent index of pypi.org simply with:

$ twine upload dist/*

Optionally, you can also sign the files in your package with a GPG by:

$ twine upload dist/* --sign

setup.py 是 Python 对多平台安装程序和 make 文件的回应。

如果您熟悉命令行安装,那么 make && make install 转换为 python setup.py build && python setup.py 安装

有些包是纯Python的,并且仅是字节编译的。其他可能包含本机代码,这将需要本机编译器(例如 gcccl)和 Python 接口模块(例如 swig >耐热玻璃)。

setup.py is Python's answer to a multi-platform installer and make file.

If you’re familiar with command line installations, then make && make install translates to python setup.py build && python setup.py install.

Some packages are pure Python, and are only byte compiled. Others may contain native code, which will require a native compiler (like gcc or cl) and a Python interfacing module (like swig or pyrex).

如果您下载的包的根文件夹中包含“setup.py”,则可以通过运行来安装它。

python setup.py install

如果您正在开发项目并且想知道该文件的用途,请检查 有关编写安装脚本的 Python 文档

If you downloaded package that has "setup.py" in root folder, you can install it by running

python setup.py install

If you are developing a project and are wondering what this file is useful for, check Python documentation on writing the Setup Script

setup.py 是一个 Python 脚本,通常与用该语言编写的库或程序一起提供。其目的是正确安装软件。

许多软件包将 distutils 框架与 setup.py 结合使用。

http://docs.python.org/distutils/

setup.py is a Python script that is usually shipped with libraries or programs, written in that language. It's purpose is the correct installation of the software.

Many packages use the distutils framework in conjuction with setup.py.

setup.py可以在两种场景下使用,一是要安装Python包。其次,您想要创建自己的 Python 包。通常标准 Python 包有几个重要的文件,如 setup.py、setup.cfg 和 Manifest.in。当您创建Python包时,这三个文件将确定(egg-info文件夹下的PKG-INFO中的内容)名称、版本、描述、其他所需的安装(通常在.txt文件中)和一些其他参数。 setup.cfg 在创建包时由 setup.py 读取(可以是 tar.gz )。您可以在 Manifest.in 中定义包中应包含的内容。无论如何,你可以使用 setup.py 做很多事情,比如

python setup.py build
python setup.py install
python setup.py sdist <distname> upload [-r urltorepo]  (to upload package to pypi or local repo)

还有很多其他命令可以与 setup.py 一起使用。寻求帮助

python setup.py --help-commands

setup.py can be used in two scenarios , First, you want to install a Python package. Second, you want to create your own Python package. Usually standard Python package has couple of important files like setup.py, setup.cfg and Manifest.in. When you are creating the Python package, these three files will determine the (content in PKG-INFO under egg-info folder) name, version, description, other required installations (usually in .txt file) and few other parameters. setup.cfg is read by setup.py while package is created (could be tar.gz ). Manifest.in is where you can define what should be included in your package. Anyways you can do bunch of stuff using setup.py like

python setup.py build
python setup.py install
python setup.py sdist <distname> upload [-r urltorepo]  (to upload package to pypi or local repo)

There are bunch of other commands which could be used with setup.py . for help

python setup.py --help-commands

setup.py 是一个与其他文件一样的 Python 文件。它可以采用任何名称,但按照惯例,它被命名为 setup.py,以便每个脚本没有不同的过程。

setup.py 最常用于安装 Python 模块,但用于其他目的:

模块:

也许这是 setup.py 最著名的用法是在模块中。虽然它们可以使用 pip 安装,但旧的 Python 版本默认不包含 pip,需要单独安装。

如果您想安装模块但不想安装 pip,唯一的选择是从 setup.py 文件安装模块。这可以通过 python setup.py install 来实现。这会将 Python 模块安装到根字典(没有 pipeasy_install 等)。

pip失败时经常使用此方法。例如,如果无法通过 pip 获取所需包的正确 Python 版本(可能是因为它不再维护),则下载源代码并运行 python setup.py install 将会执行相同的操作,除非需要编译二进制文件(但将忽略 Python 版本 - 除非返回错误)。

setup.py 的另一个用途是从源安装包。如果模块仍在开发中,则轮文件将不可用,唯一的安装方法是直接从源安装。

构建Python扩展:

构建模块后,可以使用distutils 安装脚本。构建完成后,可以使用上面的命令安装它们。

安装脚本很容易构建,一旦文件被正确配置,就可以通过运行 python setup.py build 进行编译(请参阅所有命令的链接)。

为了便于使用和按照惯例,它再次被命名为 setup.py,但可以采用任何名称。

Cython:

setup.py 文件的另一个著名用途包括编译扩展。这些需要具有用户定义值的设置脚本。它们允许快速(但一旦编译就依赖于平台)执行。这是来自 文档

from distutils.core import setup
from Cython.Build import cythonize

setup(
    name = 'Hello world app',
    ext_modules = cythonize("hello.pyx"),
)

可以通过python setup.py build编译

Cx_Freeze:

另一个需要安装脚本的模块是cx_Freeze 。这会将 Python 脚本转换为可执行文件。这允许许多命令(例如描述、名称、图标、包)包含、排除等,并且一旦运行将生成可分发的应用程序。 文档中的示例:

import sys
from cx_Freeze import setup, Executable
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]} 

base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "guifoo",
        version = "0.1",
        description = "My GUI application!",
        options = {"build_exe": build_exe_options},
        executables = [Executable("guifoo.py", base=base)])

可以通过 python 进行编译setup.py 构建

那么什么是 setup.py 文件?

很简单,它是一个在 Python 环境中构建或配置某些内容的脚本。

分发时的包应仅包含一个安装脚本,但将多个安装脚本组合在一起并形成一个安装脚本的情况并不罕见。请注意,这通常涉及 distutils 但并非总是如此(正如我在上一个示例中所示)。需要记住的是,它只是以某种方式配置 Python 包/脚本。

它采用名称,因此在构建或安装时始终可以使用相同的命令。

setup.py is a Python file like any other. It can take any name, except by convention it is named setup.py so that there is not a different procedure with each script.

Most frequently setup.py is used to install a Python module but server other purposes:

Modules:

Perhaps this is most famous usage of setup.py is in modules. Although they can be installed using pip, old Python versions did not include pip by default and they needed to be installed separately.

If you wanted to install a module but did not want to install pip, just about the only alternative was to install the module from setup.py file. This could be achieved via python setup.py install. This would install the Python module to the root dictionary (without pip, easy_install ect).

This method is often used when pip will fail. For example if the correct Python version of the desired package is not available via pipperhaps because it is no longer maintained, , downloading the source and running python setup.py install would perform the same thing, except in the case of compiled binaries are required, (but will disregard the Python version -unless an error is returned).

Another use of setup.py is to install a package from source. If a module is still under development the wheel files will not be available and the only way to install is to install from the source directly.

Building Python extensions:

When a module has been built it can be converted into module ready for distribution using a distutils setup script. Once built these can be installed using the command above.

A setup script is easy to build and once the file has been properly configured and can be compiled by running python setup.py build (see link for all commands).

Once again it is named setup.py for ease of use and by convention, but can take any name.

Cython:

Another famous use of setup.py files include compiled extensions. These require a setup script with user defined values. They allow fast (but once compiled are platform dependant) execution. Here is a simple example from the documentation:

from distutils.core import setup
from Cython.Build import cythonize

setup(
    name = 'Hello world app',
    ext_modules = cythonize("hello.pyx"),
)

This can be compiled via python setup.py build

Cx_Freeze:

Another module requiring a setup script is cx_Freeze. This converts Python script to executables. This allows many commands such as descriptions, names, icons, packages to include, exclude ect and once run will produce a distributable application. An example from the documentation:

import sys
from cx_Freeze import setup, Executable
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]} 

base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "guifoo",
        version = "0.1",
        description = "My GUI application!",
        options = {"build_exe": build_exe_options},
        executables = [Executable("guifoo.py", base=base)])

This can be compiled via python setup.py build.

So what is a setup.py file?

Quite simply it is a script that builds or configures something in the Python environment.

A package when distributed should contain only one setup script but it is not uncommon to combine several together into a single setup script. Notice this often involves distutils but not always (as I showed in my last example). The thing to remember it just configures Python package/script in some way.

It takes the name so the same command can always be used when building or installing.

当您使用 setup.py 下载软件包时,打开终端(Mac、Linux)或命令提示符(Windows)。使用cd并帮助您使用Tab按钮将路径设置为您下载文件的文件夹以及setup.py

iMac:~ user $ cd path/pakagefolderwithsetupfile/

按回车键,您应该看到一些内容像这样:

iMac:pakagefolderwithsetupfile user$

然后在 python setup.py install 之后输入:

iMac:pakagefolderwithsetupfile user$ python setup.py install

enter。完毕!

When you download a package with setup.py open your Terminal (Mac,Linux) or Command Prompt (Windows). Using cd and helping you with Tab button set the path right to the folder where you have downloaded the file and where there is setup.py :

iMac:~ user $ cd path/pakagefolderwithsetupfile/

Press enter, you should see something like this:

iMac:pakagefolderwithsetupfile user$

Then type after this python setup.py install :

iMac:pakagefolderwithsetupfile user$ python setup.py install

Press enter. Done!

为了简单起见,当您调用 安装函数提到的其他答案。在 setup.py 中,您应该放置安装软件包所需的所有内容。

常见的 setup.py 函数

以下两节讨论许多 setup.py 模块具有的两件事。

setuptools.setup

此函数允许您指定项目属性,例如项目名称、版本....最重要的是,此函数允许您安装其他正确打包的函数。有关 setuptools.setup 的示例,请参阅此网页

setuptools.setup 的这些属性允许安装这些类型的包:

自定义函数

理想情况下的 世界,setuptools.setup 将为您处理一切。不幸的是情况并非总是如此。有时您必须执行特定的操作,例如使用 subprocess 命令安装依赖项,以让您要安装的系统处于适合您的软件包的正确状态。尽量避免这种情况,这些函数会变得混乱,并且在 操作系统 和甚至分发

To make it simple, setup.py is run as "__main__" when you call the install functions the other answers mentioned. Inside setup.py, you should put everything needed to install your package.

Common setup.py functions

The following two sections discuss two things many setup.py modules have.

setuptools.setup

This function allows you to specify project attributes like the name of the project, the version.... Most importantly, this function allows you to install other functions if they're packaged properly. See this webpage for an example of setuptools.setup

These attributes of setuptools.setup enable installing these types of packages:

  • Packages that are imported to your project and listed in PyPI using setuptools.findpackages:

    packages=find_packages(exclude=["docs","tests", ".gitignore", "README.rst","DESCRIPTION.rst"])

  • Packages not in PyPI, but can be downloaded from a URL using dependency_links

    dependency_links=["http://peak.telecommunity.com/snapshots/",]

Custom functions

In an ideal world, setuptools.setup would handle everything for you. Unfortunately this isn't always the case. Sometimes you have to do specific things, like installing dependencies with the subprocess command, to get the system you're installing on in the right state for your package. Try to avoid this, these functions get confusing and often differ between OS and even distribution.

毁我热情 2024-08-13 06:46:44

要安装您下载的 Python 包,您需要解压存档并运行其中的 setup.py 脚本:

python setup.py install

对我来说,这一直感觉很奇怪。将包管理器指向下载会更自然,就像在 Ruby 和 Nodejs 中所做的那样,例如。 gem install Rails-4.1.1.gem

包管理器也更舒服,因为它熟悉且可靠。另一方面,每个 setup.py 都是新颖的,因为它是特定于包的。它需要对约定的信心“我相信这个 setup.py 与我过去使用过的其他命令采用相同的命令”。这对精神意志力来说是一种令人遗憾的负担。

我并不是说 setup.py 工作流程不如包管理器安全(我理解 Pip 只是在里面运行 setup.py),但我当然觉得它很尴尬和不和谐。所有命令都指向同一个包管理器应用程序,这是一种和谐。您甚至可能会喜欢它。

To install a Python package you've downloaded, you extract the archive and run the setup.py script inside:

python setup.py install

To me, this has always felt odd. It would be more natural to point a package manager at the download, as one would do in Ruby and Nodejs, eg. gem install rails-4.1.1.gem

A package manager is more comfortable too, because it's familiar and reliable. On the other hand, each setup.py is novel, because it's specific to the package. It demands faith in convention "I trust this setup.py takes the same commands as others I have used in the past". That's a regrettable tax on mental willpower.

I'm not saying the setup.py workflow is less secure than a package manager (I understand Pip just runs the setup.py inside), but certainly I feel it's awkard and jarring. There's a harmony to commands all being to the same package manager application. You might even grow fond it.
