python - Django:导入错误:没有名为 pocdebug_toolbar 的模块

Question

从 uWSGI 启动 Django 时出现此错误，并且无法找出问题所在:

...
File "/usr/local/lib/python2.7/dist-packages/django/utils/translation/trans_real.py", line 160, in _fetch
    app = import_module(appname)
File "/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py", line 35, in import_module
    __import__(name)
ImportError: No module named pocdebug_toolbar

Python 2.7.3； Django ==1.4.3； Ubuntu 12.04.2 LTS

Here is the full traceback:

已解决。我忘记了 settings.py INSTALLED_APPS 元组中应用程序之间的逗号，因此它将两个字符串“poc”和“debug_toolbar”连接成“pocdebug_toolbar”。

INSTALLED_APPS = (
   ...
   'poc'  # <== missing comma here
   'debug_toolbar'
   )
