python - Django manage.py runserver 语法无效

Question

我正在使用 django 在 Ubuntu 中开发一个网络。一切正常。现在，我想更换使用 Windows 的计算机。当我尝试运行服务器时，它给出:

E:\DEGNet>py manage.py runserver
  File "manage.py", line 14
    ) from exc
         ^
SyntaxError: invalid syntax

E:\DEGNet>py
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)]
 on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

如上所示，我已经安装了Python 3.6.3。我也使用 pip3 安装了 django 和其他必要的库。

编辑:manage.py文件，是我生成项目时默认得到的manage.py

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "DEGNet.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)

我遇到了同样的问题，但现在用这个 cmd 解决了:

python3 manage.py runserver
