Question

好的，我已经使用pip3在我的virtualenv中安装了pymongo，并且当我尝试在我的flask应用程序中加载pymongo模块时（仅当我使用自己的域运行它时，我仍然无法在我的烧瓶中运行flask公共IP）页面返回500 Internal Server Error。

这是错误

Answer 1

确保使用python 2的pip而不是pip3来安装依赖项。出于某种原因（默认配置），apache不会使用pip3依赖项来运行应用程序。

$ sudo apt-get install python-pip
$ sudo pip install flask
$ sudo pip install pymongo
