python check_output 文件未找到错误 : [WinError 2] The system cannot find the file specified

Question

我正在运行下一段代码来检查文件的类型:

import subprocess as sub
output = sub.check_output(["file", "test.py"]).decode('ascii')   
#output=sub.check_output(["file","C:/Users/Roger.That/PycharmProjects/test/test.py"]).decode('ascii')

我不断收到以下错误:

Traceback (most recent call last):

  File "C:/Users/Roger That/PycharmProjects/test/test.py", line 2, in <module>
    output = sub.check_output(["file", "test.py"]).decode('ascii')
  File "C:\Users\Roger That\AppData\Local\Programs\Python\Python37-32\lib\subprocess.py", line 395, in check_output
    **kwargs).stdout
  File "C:\Users\Roger That\AppData\Local\Programs\Python\Python37-32\lib\subprocess.py", line 472, in run
    with Popen(*popenargs, **kwargs) as process:

    restore_signals, start_new_session)
  File "C:\Users\Roger That\AppData\Local\Programs\Python\Python37-32\lib\subprocess.py", line 1178, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

我的 test.py 的完整路径:"C:/Users/Roger.That/PycharmProjects/test/test.py"

gitbash 的输出:

$ file /c/Users/Roger\ That/PycharmProjects/test/test.py
/c/Users/Roger That/PycharmProjects/test/test.py: ASCII text, with CRLF line terminators

有没有可能与我在“Roger”和“That”之间有一个点有关？虽然当我使用相对路径(仅文件名)时它也不起作用

更新

我将用户的目录名称从 Roger that 更改为 Roger.that，但仍然没有帮助:

python /c/Users/Roger.That/PycharmProjects/test/test.py
same error..

还检查了:

import subprocess as sub
output = sub.check_output(["ls" "-l"])

遇到同样的错误

我从头开始创建了虚拟环境，它解决了我的问题。
