Django 1.5b1：执行django-admin.py会导致“No modules named settings”错误

问题描述

我刚刚安装了Django-1.5b1。
我的系统配置：

• OSX 10.8


• Python 2.7.1


• Virtualenv 1.7.2

当我打电话给 django-admin.py 命令我得到以下错误

 （devel）ninja Django-1.5b1：django-admin.py 
用法： django-admin.py子命令[options] [args]

解决方案
我在启动新项目时遇到了同样的问题。 
我通过在命令提示符下给出这个命令来解决问题：
  export DJANGO_SETTINGS_MODULE = 
  
以这种方式我取消设置指向设置 文件（使用 env | grep DJANGO_SETTINGS_MODULE 发现）在开始使用 virtualenv 
之前设置
 
 
 
在取消设置变量后， django-admin.py 脚本的工作就像一个魅力！

Did anyone have the same errors? Can anyone advise or help with it?
Thanks,

 解决方案 
I had the same issue when starting a new project.I solved the problem by giving this command at the command prompt:
export DJANGO_SETTINGS_MODULE=
in this way I unset the variable that was pointing to a "settings" file (discovered using env | grep DJANGO_SETTINGS_MODULE) I set before starting using virtualenv
after unsetting the variable the django-admin.py script worked like a charm!
