python-2.7 - manage.py文件显示无效的语法错误

Question

在本地计算机上运行应用程序时，我的应用程序运行良好。但是，一旦我将其上传到服务器上，manage.py就会出现以下错误-

File "manage.py", line 14 ) from exc ^ SyntaxError: invalid syntax

这是manage.py的代码-

import os
import sys

if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "chatbot.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 ***//Here is the error***
execute_from_command_line(sys.argv)

我正在使用Python 2.7和Django 1.11

请引用此链接:How to solve SyntaxError on autogenerated manage.py?

从上面的链接中学到的是，如果我们有两个版本的python，则需要指定运行应用程序的版本，如下所示:

 python3 manage.py runserver
