安装后使用django导入南部时出错

Question

这是我第一次使用Django和South。

我用pip安装了南V1.01，但是当我跑的时候     manage.py schemamigration myapp --initial

我得到了

File "manage.py", line 11, in <module>
execute_from_command_line(sys.argv)
File "/Library/Python/2.7/site-packages/django/core/management/__init__.py",     
line 385, in execute_from_command_line
utility.execute()
File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", 
line 354, in execute
django.setup()
File "/Library/Python/2.7/site-packages/django/__init__.py", line 21, in setup
apps.populate(settings.INSTALLED_APPS)
File "/Library/Python/2.7/site-packages/django/apps/registry.py", line 85, in 
populate
app_config = AppConfig.create(entry)
File "/Library/Python/2.7/site-packages/django/apps/config.py", line 87, in   
create module = import_module(entry)
File     
     "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module __import__(name)

我在settings.py中的INSTALLED_APPS下添加了myapp，我可以看到South已正确安装。

如果有人能告诉我在哪里寻找修复，我将不胜感激。
