Django启动时不报错解决方案

项目启动时有报错，但是无法知道具体信息：

[root@Master new_project]# python3 manage.py runserver
Watching for file changes with StatReloader
Exception in thread django-main-thread:
Traceback (most recent call last):
  File "/usr/local/python3/lib/python3.8/threading.py", line 932, in _bootstrap_inner
    self.run()
  File "/usr/local/python3/lib/python3.8/threading.py", line 870, in run
    self._target(*self._args, **self._kwargs)

    fn(*args, **kwargs)

    raise _exception[1]
  File "/usr/local/python3/lib/python3.8/site-packages/django/core/management/__init__.py", line 394, in execute
    autoreload.check_errors(django.setup)()
  File "/usr/local/python3/lib/python3.8/site-packages/django/utils/autoreload.py", line 64, in wrapper
    fn(*args, **kwargs)
  File "/usr/local/python3/lib/python3.8/site-packages/django/__init__.py", line 24, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/usr/local/python3/lib/python3.8/site-packages/django/apps/registry.py", line 84, in populate
    raise RuntimeError("populate() isn't reentrant")
RuntimeError: populate() isn't reentrant

　　解决方法，把最后一行的报错文件的对应行数里面的内容raise RuntimeError("populate() isn't reentrant")替换成self.app_configs = {}，报错立显！
