研发总结记录：处理Django中的错误 django.core.exceptions.ImproperlyConfigured

在运行项目，准备迁移时出现的如下错误：

Traceback (most recent call last):

  File "C:\py3_env\lib\site-packages\django\apps\config.py", line 107, in create

    entry = module.default_app_config

AttributeError: module 'restful' has no attribute 'default_app_config'

 

During handling of the above exception, another exception occurred:

 

Traceback (most recent call last):

    "with a 'path' class attribute." % (module, paths))

django.core.exceptions.ImproperlyConfigured: The app module has multiple filesystem locations (['C:\\***\\restful', 'C:/***\\restful']); you must configure this app with an AppConfig subclass with a 'path' class attribute.

 

解决方案：

出现这种错误的原因之一是因为在Django工程路径中找不到此app的路径，需要在此app下新建一个包文件__init__.py 即可解决此问题。
