从命令行运行Python脚本会在默认文本编辑器中打开脚本,而不是执行脚本

Question

从命令行运行Python脚本会在默认文本编辑器中打开脚本,而不是执行脚本

Pio*_*ost 6 python windows command-line file-association

我有.py扩展名与Python解释器相关的文件.但是,当我在命令行键入此类文件的名称并按下ENTER该文件时,将在默认文本编辑器(Notepad ++)中打开该文件,而不是使用关联的Python解释器运行.为什么？

Z:\1>where python
c:\Program Files\Python\2.7\python.exe

Z:\1>reg query HKCR\.py /ve

HKEY_CLASSES_ROOT\.py
    (Default)    REG_SZ    Python.File


Z:\1>reg query HKCR\Python.File\shell\open\command /ve

HKEY_CLASSES_ROOT\Python.File\shell\open\command
    (Default)    REG_SZ    c:\Program Files\Python\2.7\python.exe "%1" %*


Z:\1>echo %PATHEXT%
.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY;.PYW

Z:\1>type a.py
from __future__ import print_function; import sys; print(sys.executable); print(sys.version)
Z:\1>a.py    <--- this opens a.py in the default text editor

我使用的是Windows Vista x64 Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32

UPDATE

删除HKEY_CLASSES_ROOT\Unknown\shell\notepad++\command密钥后(我在过去创建了这个密钥,以便在没有扩展名的情况下将文件与Notepad ++相关联 - 请参阅如何设置默认程序,在Windows中没有扩展名的情况下打开文件？),其值为C:\Program Files (x86)\Notepad++\notepad++ %1I得到此错误:

此文件没有与之关联的程序来执行此操作.在"设置关联"控制面板中创建关联.

要显示系统正常使用的所有注册表项,以找出与.py扩展相关联的程序,请运行以下批处理文件(python_assoc.query.bat):

@echo off

) else (
    set keypath=HKCR
    echo ----- HKEY_CLASSES_ROOT -----

我还运行Process Monitor(感谢Maximus),以查看a.py从命令行运行时正在读取的注册表项.我设置过滤器只包括cmd.exe用于运行a.py文件的pid 和排除类型的操作RegCloseKey.

通常，我将确保当前用户的设置不会覆盖该关联：

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\UserChoice
HKCU\Software\Classes\.py
HKCU\Software\Classes\Python.File

但是，当我阅读更新中的Process Monitor输出时，似乎没有HKCU在系统上定义任何这些键。

我的下一步是在提升的cmd控制台中运行以下命令：

> assoc .PY=Python.File
> ftype Python.File=c:\Program Files\Python\2.7\python.exe "%1" %*

据我所知，这将设置系统关联，HKLM\Software\Classes并且什么也不做。根据您问题中的信息，似乎已经正确设置了。所以，我不知道是什么或者assoc或ftype做来解决这个问题。
