管理py运行服务器导入程序

Question

运行python后manage.pyrunserver0.0.0.0:8000

我收到了这个错误消息

Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x7fefc10b9190>>

    from django.contrib.auth import get_permission_codename
ImportError: cannot import name get_permission_codename

我已经签出/django/contrib/auth/management/init。py和get_permission_codename函数存在，所以我看不出为什么不导入它。

首先，确保已安装Django 1.6或更高版本，因为此时添加了get\u permission\u codename。

问题可能出在旧的pyc文件上。您可以通过完全卸载Django然后重新安装来消除这些问题。
