Flask 路由返回 500 错误
Flask routes returning 500 errors
所以我正在尝试将我的 python flask 应用程序部署到 ubuntu AWS EC2 实例。我已经设置 mod_wsgi，配置了虚拟主机设置 virtualenv 并创建了别名来为我的静态文件提供服务。出于某种原因，我无法为我的 api 路由获取我的自定义 url 到 return 的正确信息。我已经尝试了所有搜索过的方法，这是我最后的选择。

事实证明这是我如何实例化 uwsgi 的问题。我从头开始删除了所有内容，并使用 uwsgi 完成了烧瓶安装说明，并且能够使所有内容正常工作。
