Question

我正在尝试使用subprocess调用python程序，但是出现权限错误。我尝试以管理员身份运行PyCharm，但这无济于事。

我的代码：

answer = subprocess.check_output("../folder python program %s %s" %(valueA, valueB), encoding = 'utf8')

错误：

Traceback (most recent call last):
  File "C:/Users/User/PycharmProjects/a/b/b_resolution.py", line 35, in <module>
    answer = subprocess.check_output("../folder python program %s %s" %(valueA, valueB), encoding = 'utf8')
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\Lib\subprocess.py", line 376, in check_output
    **kwargs).stdout
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\Lib\subprocess.py", line 453, in run
    with Popen(*popenargs, **kwargs) as process:
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\Lib\subprocess.py", line 756, in __init__
    restore_signals, start_new_session)
  File "C:\Users\User\AppData\Local\Programs\Python\Python37-32\Lib\subprocess.py", line 1155, in _execute_child
    startupinfo)
PermissionError: [WinError 5] Access Denied

有人知道我该如何解决此权限错误？

Answer 1

检查当前用户的文件权限。

右键单击文件，在安全性方面，您可以查看用户的文件权限。

如果您没有权限读取文件，请依次选择“高级”>“选择主体”，然后选择check this doc.

Answer 2

我自己解决了问题，python命令位于路径之前。像这样：

answer = subprocess.check_output("python ../folder program %s %s" %(valueA, valueB), encoding = 'utf8')

但是我有一个问题，它说：

can't find '__main__' module in '../pydig'

通过编写路径中包含的程序名称也解决了该问题：

answer = subprocess.check_output("python ../folder/program %s %s" %(valueA, valueB), encoding = 'utf8')

PermissionError：[WinError 5]访问被拒绝
