有趣的是这是以前工作，但不知何故因为
Funny thing is this used to work but somehow broke due to some changes in the project.
看起来你在 INSTALLED_APPS >中缺少一个逗号， code>设置。
It looks like you are missing a comma in your INSTALLED_APPS setting.
而不是：
INSTALLED_APPS = (
...
'analysis'
'debug_toolbar',
...
)
应该是：
INSTALLED_APPS = (
...
'analysis',
'debug_toolbar',
...
)
当您忘记逗号时，Python将'analysis'和'debug_toolbar'插入字符串 analysisdebug_toolbar 。在Python中，最好在列表或元组的最后一个元素中加入一个逗号。它允许您添加新项目或重新排列顺序，而不会遇到这样的错误。
When you forget the comma, Python concatonates 'analysis' and 'debug_toolbar' into the string analysisdebug_toolbar. In Python, it's a good idea to include a trailing comma in the last element in your list or tuple. It allows you to add new items or rearrange the order without hitting bugs like this.
