Windows 不会将命令行参数传递给从 shell 执行的 Python 程序

发布于 2024-08-28 21:53:44 字数 593 浏览 5 评论 0原文

如果我尝试从 Windows 命令 shell 直接将命令行参数作为可执行命令执行，则在将命令行参数传递给 Python 程序时遇到问题。例如，如果我有这个程序（test.py）：

import sys
print "Args: %r" % sys.argv[1:]

并执行：

>test foo
Args: []

与：

>python test.py foo
Args: ['foo']

我的配置有：

PATH=...;C:\python25;...
PATHEXT=...;.PY;....

>assoc .py
.py=Python.File

>ftype | grep Python
Python.CompiledFile="C:\Python25\python.exe" "%1" %*
Python.File="C:\Python25\python.exe" "%1" %*
Python.NoConFile="C:\Python25\pythonw.exe" "%1" %*
原文

I'm having trouble getting command line arguments passed to Python programs if I try to execute them directly as executable commands from a Windows command shell. For example, if I have this program (test.py):

import sys
print "Args: %r" % sys.argv[1:]

And execute:

>test foo
Args: []

as compared to:

>python test.py foo
Args: ['foo']

My configuration has:

PATH=...;C:\python25;...
PATHEXT=...;.PY;....

>assoc .py
.py=Python.File

>ftype | grep Python
Python.CompiledFile="C:\Python25\python.exe" "%1" %*
Python.File="C:\Python25\python.exe" "%1" %*
Python.NoConFile="C:\Python25\pythonw.exe" "%1" %*

最初的梦 2024-09-04 21:53:44

我想我解决了这个问题。由于某种原因，注册表中有第二个位置（除了存储在 HKEY_CLASSES_ROOT\Python.File\shell\open\command 中的文件关联所示的位置之外）：

[HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command]
@="\"C:\\Python25\\python.exe\" \"%1\" %*"

这似乎是我系统上的控制设置。上面的注册表设置添加了“%*”以将所有参数传递给 python.exe（由于某种原因它在我的注册表中丢失了）。

I think I solved this. For some reason there is a SECOND place in the registry (besides that shown by the file associations stored in HKEY_CLASSES_ROOT\Python.File\shell\open\command):

[HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command]
@="\"C:\\Python25\\python.exe\" \"%1\" %*"

This seems to be the controlling setting on my system. The registry setting above adds the "%*" to pass all arguments to python.exe (it was missing in my registry for some reason).

对于 Windows 7 上的 Python 3.3，我的设置位于另一个注册表项下；我为使参数通过而更改的键是

HKEY_USERS\S-1-5-21-3922133726-554333396-2662258059-1000_Classes\py_auto_file\shell\open\command

它是 "C :\Python\Python33\python.exe" "%1"。我只附加了 %* 。该键的值现在为“C:\Python\Python33\python.exe”“%1”%*。

我还有几个（至少五个）其他键，其值为 "C:\Python\Python33\python.exe" "%1"，但这是我更改的使其起作用的键。

For Python 3.3 on Windows 7, my setting was under another registry key; the key I changed to make the arguments get passed was

HKEY_USERS\S-1-5-21-3922133726-554333396-2662258059-1000_Classes\py_auto_file\shell\open\command

It was "C:\Python\Python33\python.exe" "%1". I only appended %* to it. The key's value is now "C:\Python\Python33\python.exe" "%1" %*.

I had several (at least five) other keys with the value "C:\Python\Python33\python.exe" "%1", but this is the one I changed that made it work.

我的设置位于另一个注册表项 HKEY_CLASSES_ROOT\py_auto_file 下。提到的其他键也存在，但 Windows 由于某种原因使用了这个键。

My setting was under yet another registry key, HKEY_CLASSES_ROOT\py_auto_file. The other keys mentioned also existed, but Windows was using this one for some reason.

为了让它为我工作，我必须使用注册表路径：

HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

并添加 %*

To make it working for me, I had to use the registry path:

奈何桥上唱咆哮 2024-09-04 21:53:44

如果在我的 Windows 10 系统上通过编辑以下注册表项来修复此问题：

Computer\HKEY_CLASSES_ROOT\py_auto_file\shell\open\command
Computer\HKEY_CLASSES_ROOT\Python.File\Shell\Open\Command
Computer\HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command

为此值：

"C:\Python27\python.exe" "%1" %*

If fixed this on my Windows 10 system by editing the following registry keys:

Computer\HKEY_CLASSES_ROOT\py_auto_file\shell\open\command
Computer\HKEY_CLASSES_ROOT\Python.File\Shell\Open\Command
Computer\HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command

只是在用心讲痛 2024-09-04 21:53:44

非常感谢大多数其他答案帮助我找到解决方案！

我的情况是使用 py.exe 打开 .py 文件（不是直接使用 python.exe），这种情况在几个例子中都提到过评论，但我决定将其作为单独的答案发布以强调差异。

所以我有与 C:\Windows\py.exe 关联的 .py 文件，并在 C:\Windows\py.ini 配置中我有几个 shebang 定义

[commands]
<my_venv_py> = C:\Programs\my_venv_py\Scripts\python.exe
<my_venv_py_w> = C:\Programs\my_venv_py\Scripts\pythonw.exe

可以在我的脚本中使用，例如 #!。

在 Microsoft Windows 7 [版本 6.1.7601] 上，我的 python 脚本没有收到这样的参数，

script.py 1 2

但这工作正常

py script.py 1 2

文件关联没问题

> assoc .py
.py=Python.File

> ftype | grep Python
File STDIN:
Python.CompiledFile="C:\Windows\py.exe" "%1" %*
Python.File=C:\Windows\py.exe "%L" %*
Python.NoConFile="C:\Windows\pyw.exe" "%1" %*

我已经尝试了很多注册表更改，但最后的帮助是以下更改（保存到 .reg 文件并运行）。我发现此注册表项正在搜索具有初始值 "C:\Windows\py.exe" "%1" 的 "%1" 字符串，并添加了 % * 最后作为其他答案注意：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\py.exe\shell\open\command]
@="\"C:\\Windows\\py.exe\" \"%1\" %*"

有关信息，在我尝试设置这些键和值之前并没有帮助（至少在上面提到之前）：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.py]
@="Python.File"
[HKEY_CURRENT_USER\Software\Classes\.py]
@="Python.File"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.py]
@="Python.File"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py]
@="Python.File"

[HKEY_CLASSES_ROOT\py_auto_file]
@="Python File"
[HKEY_CLASSES_ROOT\py_auto_file\shell\open\command]
@="\"C:\\Windows\\py.exe\" \"%1\" %*"

[HKEY_CLASSES_ROOT\Python.File]
@="Python File"
[HKEY_CLASSES_ROOT\Python.File\Shell\Open\command]
@="\"C:\\Windows\\py.exe\" \"%1\" %*"

A lot of thanks for the most of other answers for helping me to find the solution!

My case was to open .py-files with py.exe (not python.exe directly), this case it noted in a couple of comments, but I decided to post this as a separate answer to emphasize the difference.

So I have my .py-files associated with C:\Windows\py.exe and in C:\Windows\py.ini config I have a couple of shebang definitions

[commands]
<my_venv_py> = C:\Programs\my_venv_py\Scripts\python.exe
<my_venv_py_w> = C:\Programs\my_venv_py\Scripts\pythonw.exe

to use in my scripts like this #!<MY_VENV_PY>.

And on Microsoft Windows 7 [Version 6.1.7601] my python script did NOT received the args like this

script.py 1 2

but this worked fine

py script.py 1 2

File associations were OK

> assoc .py
.py=Python.File

> ftype | grep Python
File STDIN:
Python.CompiledFile="C:\Windows\py.exe" "%1" %*
Python.File=C:\Windows\py.exe "%L" %*
Python.NoConFile="C:\Windows\pyw.exe" "%1" %*

I've tried much of registry changes, but the last helped was the following change (saved to a .reg-file and run). I've found this registry key searching "%1" string with initial value "C:\Windows\py.exe" "%1" and added %* in the end as other answers note:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\py.exe\shell\open\command]
@="\"C:\\Windows\\py.exe\" \"%1\" %*"

For information, before I tried to setup these keys and values and did not helped (at least before the noted above):

我使用 python.exe 和 py_auto_file 检查了所有注册表项，并使它们指向我当前的 python 安装，包括末尾的 %*论据。他们有不少：

但这并没有完成工作我。我还必须更改我的默认 python 应用程序。

But that didn't do the job for me. I had to change my default python application as well.

Application dialog

As one can see I have 3 Python versions installed. It is impossible to see which is which here so I tried all three of them as my default python application. Eventually I was able to get my script arguments with one of these three.

通过查看 Windows 注册表，我发现了所有类似的地方
出现 Python36\pythonw.exe "%1" %*。

当我在命令提示符下输入 python app.py args 时，一切正常。

当我仅使用应用程序名称 (app.py args) 时，Windows 在 Python 中打开 app.py，但应用程序在尝试访问 argv[1] 时失败，因为 len(argv) 为 1。

显然 Windows 知道足以将 py 文件传递​​给 Python，但我无法通过查看注册表项来弄清楚它是如何构造命令的。它似乎使用的是 "%1" 而不是 "%1" %*。

By looking through the Windows registry, I found all the places where anything like
Python36\pythonw.exe "%1" %* appears.

When I type python app.py args at the command prompt, everything works properly.

When I use just the app name (app.py args) Windows opens app.py in Python, but the app fails when it tries to access argv[1], because len(argv) is 1.

Apparently Windows knows enough to pass a py file to Python, but I can't figure out from looking at registry entries how it constructs the command. It appears to be using "%1" rather than "%1" %*.
