Question

我只是测试如何从一个.py文件调用外部.py文件。我有2个.py文件，都在同一目录中。这是主要的代码（runext.py假设调用ext.py）：

import subprocess
subprocess.call("/Users/training/PycharmProjects/MarcouFirstProject/ext.py")

ext.py只是print("hey this actually worked")

但是，每次运行runext.py时，都会收到以下错误消息：

Traceback (most recent call last):
  File "/Users/training/PycharmProjects/MarcouFirstProject/runext.py", line 2, in <module>
    subprocess.call("/Users/training/PycharmProjects/MarcouFirstProject/ext.py")
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 557, in call
    with Popen(*popenargs, **kwargs) as p:
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 1551, in _execute_child
    raise child_exception_type(errno_num, err_msg)

PermissionError: [Errno 13] Permission denied

我不知道为什么它会拒绝许可。这是在学校的计算机上（我在编程课程中）如果有帮助的话。

感谢。

您无权执行文件/Users/training/PycharmProjects/MarcouFirstProject/ext.py

您可以使用chmod：

添加权限+x

chmod +x /Users/training/PycharmProjects/MarcouFirstProject/ext.py

或者，你可以明确地使用python：

import subprocess
subprocess.call("python /Users/training/PycharmProjects/MarcouFirstProject/ext.py")

Errno 13权限在mac上被拒绝
