尝试安装 django 调试工具栏并收到以下错误：

Traceback (most recent call last):
  File "/home/user/project/manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
  File "/home/user/project/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line
    utility.execute()
  File "/home/user/project/env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 312, in execute
django.setup()
  File "/home/user/project/env/local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup
apps.populate(settings.INSTALLED_APPS)
  File "/home/user/project/env/local/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate
app_config = AppConfig.create(entry)
  File "/home/user/project/env/local/lib/python2.7/site-packages/django/apps/config.py", line 86, in create
module = import_module(entry)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
__import__(name)
ImportError: No module named analysisdebug_toolbar

软件包版本：

Django==1.8.2
django-debug-toolbar==1.3.0

有趣的是，这曾经可以工作，但由于项目的一些变化而以某种方式中断。

您的设置中似乎缺少逗号INSTALLED_APPS。

代替：

INSTALLED_APPS = (
    ...
    'analysis'
    'debug_toolbar',
    ...
)

它应该是：

INSTALLED_APPS = (
    ... 
    'analysis',
    'debug_toolbar',
    ...
)

当您忘记逗号时，Python 会连接'analysis'并'debug_toolbar'进入字符串analysisdebug_toolbar. 在 Python 中，最好在列表或元组的最后一个元素中包含一个尾随逗号。它允许您添加新项目或重新排列订单，而不会遇到这样的错误。
