subprocess.Popen使用Unicode路径 [英] subprocess.Popen with a unicode path

问题描述

我有一个要打开的Unicode文件名。
以下代码：

I have a unicode filename that I would like to open. The following code:

cmd = u'cmd /c "C:\\Pok\xe9mon.mp3"'
cmd = cmd.encode('utf-8')
subprocess.Popen(cmd)

返回

>>> 'C:\Pokיmon.mp3' is not recognized as an internal or external command, operable program or batch file.

即使文件确实存在。为什么会发生这种情况？

even though the file do exist. Why is this happening?

推荐答案

似乎您正在使用Windows和Python2.X。使用 os.startfile ：

It looks like you're using Windows and Python 2.X. Use os.startfile:

>>> import os
>>> os.startfile(u'Pokémon.mp3')

非直观地，让命令外壳执行

Non-intuitively, getting the command shell to do the same thing is:

>>> import subprocess
>>> import locale
>>> subprocess.Popen(u'Pokémon.mp3'.encode(locale.getpreferredencoding()),shell=True)

在我的系统上，命令外壳程序（cmd.exe）编码为 cp437 ，但对于Windows程序为 cp1252 。 Popen 希望将shell命令编码为 cp1252 。这似乎是一个错误，并且似乎也已在Python 3.X中修复：

On my system, the command shell (cmd.exe) encoding is cp437, but for Windows programs is cp1252. Popen wanted shell commands encoded as cp1252. This seems like a bug, and it also seems fixed in Python 3.X:

>>> import subprocess
>>> subprocess.Popen('Pokémon.mp3',shell=True)
