ImportError:在安装django-cms时，没有名为cms的模块。

Question

我有一个基于django -cms的本地工作django项目。现在，当我激活virtualenv source env/bin/activate和runserver python manage.py runserver时，它突然失效了，我得到了ImportError: No module named cms。在这里，完全错误消息：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 354, in execute
    django.setup()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/__init__.py", line 21, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/apps/config.py", line 87, in create
    module = import_module(entry)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named cms

我不明白这一点，因为一切都很好，只有两周前我做的事情是将项目所在的目录从我的桌面放到另一个位置。任何人都知道如何解决这个问题，或者是什么原因。

移动您的virtualenv将破坏它，因为它使用绝对路径。如果您移动了其中包含virtualenv的文件夹，那么路径将不再指向virtualenv包。您需要将virtualenv放置在以前的位置，或者创建一个新的virtualenv。
