python之导入错误 : No module named modelsinspector

当我执行syncdb时出现以下错误

Traceback (most recent call last): 
  File "manage.py", line 11, in <module> 
    execute_manager(settings)

ImportError: No module named modelsinspector 

请您参考如下方法:

为什么要安装 South 0.5？ South 的当前版本是 0.7.3 - 0.5 已有两年多的历史，并且可以追溯到添加 modelsinspector 模块的重组之前。删除该版本并安装最新版本。
