Question

我突然打开了我的Django项目，当我尝试使用py manage.py runserver启动它时，它给了我这个错误。

django.core.exceptions.ImproperlyConfigured: WSGI application 'invoice_project.wsgi.application' could not be loaded; Error importing module.

这是我的追溯。我检查了settings.py和wsgi.py文件，它们（我认为）都已正确配置，因此我不知道从哪里开始寻找错误

Answer 1

您似乎缺少依赖性livereload

您可以使用

将其安装在您的应用程序虚拟环境中

pip install livereload

如果您要删除依赖项，请从 py的中间件设置中删除

@Ivan的建议，以启动应用程序而无需实时重新加载。
