如何为 popen 指定工作目录 [英] How can I specify working directory for popen

问题描述

有没有办法在Python的subprocess.Popen()中指定命令的运行目录?

Is there a way to specify the running directory of command in Python's subprocess.Popen()?

例如:

Popen('c:mytool	ool.exe', workingdir='d:	estlocal')

我的 Python 脚本位于 C:programspython

My Python script is located in C:programspython

是否可以在D: estlocal目录下运行C:mytool ool.exe?

Is is possible to run C:mytool ool.exe in the directory D: estlocal?

如何设置子进程的工作目录?

How do I set the working directory for a sub-process?

推荐答案

subprocess.Popen 采用 cwd 参数 来设置当前工作目录；您还需要转义反斜杠 ('d:\test\local')，或使用 r'd: estlocal' 以便Python 不会将反斜杠解释为转义序列.按照您编写的方式， 部分将被转换为 tab.

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\test\local'), or use r'd: estlocal' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the part will be translated to a tab.

所以，你的新行应该是这样的:

So, your new line should look like:

subprocess.Popen(r'c:mytool	ool.exe', cwd=r'd:	estlocal')

要将 Python 脚本路径用作 cwd，import os 并使用以下命令定义 cwd:

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__))
