python之运行 django-admin.py ，引发错误 "Could not import settings ' mysite.settings' "

Win 7 + python 2.7 + django 1.5.8

我不知道我对我的 PC 做了什么，但昨天 django-admin.py startproject 正在运行。我如何解决它？谢谢你的时间。

请您参考如下方法:

你所做的是添加一个环境变量 DJANGO_SETTINGS_MODULE=mysite.settings 之后，要么卸载模块，要么昨天你只运行 django-admin.py 命令来自 mysite 所在的特定目录。

解决这个问题:

解决方案 1:删除 DJANGO_SETTINGS_MODULE 环境变量(我建议这样做)

解决方案 2:从您昨天运行的目录中运行 django-admin.py 命令

解决方案 3:显式运行 django-admin.py whatever --settings=some.good.settings.module

但实际上，无论如何只做 1。这样更明智。

如果您不知道如何删除环境变量，请查看 google，它非常简单，无论如何您都应该记住它，因为您昨天已经这样做了 :P(或查看此 link
