ModulenotFoundError：无模块名为＆＃x27; ＆＃x27;

Question

我正在尝试运行python manage.py runserver，我可以

ModuleNotFoundError: No module named ' '

在这里看到全部输出：

(venv) danieljohnson@MACHPXNV2CL2Y project % python manage.py runserver

print（name）语句打印出“ .middleware”

我尝试安装/重新安装gevent，但这无效。我迷路了，因为缺少的包装是空白。有什么想法吗？

好的，所以这个问题本质上是一个错字...

我在我的设置中有这个：py：

"authentication.middleware.SetDefaultUserGroupMiddleware" if not API_MODE else None,

我不小心修复了

" .middleware.SetDefaultUserGroupMiddleware" if not API_MODE else None,

偶然删除后，一切正常，一切正常
