关于Django 报错django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates 的说明
之前工作的缘故用django (版本2.2.2)编写了一个信息登记的系统。一直稳定运行，今天突然报错。
Error occurred while reading WSGI handler:
Traceback (most recent call last):

StdErr:字面报错原因是因为WSGI错误，关闭WSGI运行测试引擎报错

django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: lib报错信息基本一致，看不出有什么问题，其它的报错内容也看不懂，就看到有一个‘APPS’，想起来前几天自己研究Django3.0版本的时候手动注册app也是报错，不知道是不是这个原因。然后百度查，发现还真是有说settings的问题。打开settings发现settings昨天刚刚更改了。昨天我是将‘lib’删除了，然后又加了，但这样等于没改过。
先不管了，将手动写入的app‘lib’删除果然好了。但是我这台电脑的Django版本并没有升级。不明白为什么之前可以正常运行现在却不行了。百度查了资料说注册app的时候会自动添加到settings里面，我看了一下我的发现第一个还真是我的app。不过不是单单写了一个‘lib’而是写成了‘lib.apps.LibConfig’，唉~自学就是坑多~写下来让别人少走些弯路吧~
