我有一个python程序，我想在我的linux机器上运行它

Question

当我运行python程序时显示如下

文件“ manage.py”，第16行），来自exc^ SyntaxError：语法无效

这是我得到的错误。

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'SkillPoint.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

Answer 1

您共享的是Django的manage.py文件。

如果使用python 2运行python manage.py <command>，您会得到提到的错误。

❯ python --version
Python 2.7.16

❯ python manage.py makemigrations
  File "manage.py", line 16
    ) from exc
         ^
SyntaxError: invalid syntax

使用Python 3，它将起作用。
