dev_appserver.py 没有启动开发服务器

Question

我一直在关注本教程，试图在 Google 应用引擎上构建应用：

https://github.com/GoogleCloudPlatform/appengine-django-skeleton

不过，当我运行 dev_appserver.py 时，我遇到了障碍，三分之二的服务器运行良好。但是开发服务器只返回 500 个错误。

确切的控制台输出如下：

ubuntu@ubuntu:~/Desktop/appengine-django-skeleton$ dev_appserver.py --port=9999 app.yaml

ImproperlyConfigured: 'django.contrib.admin.apps.AdminConfig' isn't a subclass of AppConfig.

我猜这里的关键是

ImproperlyConfigured: 'django.contrib.admin.apps.AdminConfig' isn't a subclass of AppConfig.

没有对来自 github 的文件进行任何代码更改。仅 github 页面上列出的配置更改。

我已经设法通过在virtualenv 上而不是在lib 目录中安装所有需要的模块来解决这个问题。克隆存储库后，运行此命令。

pip install -r requirements.txt
