django.core.exceptions.ImcorrectConfiguration： WSGI 应用程序'invoice_project.wsgi.application'无法加载;导入模

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。我检查了设置。

看起来您缺少依赖关系livereload

您可以使用

将其安装在您的应用程序中

pip install livereload

@ivan的建议也是有效的，如果要删除依赖关系从settings.py中的中间件设置中删除它以启动应用程序而无需实时重新加载。
