Question

我正在使用passenger在Flask REST API服务器上部署apache。

这是我的Apache conf文件：

<VirtualHost *:80>
    ServerName demo.app.com

    DocumentRoot /var/www/demo.app.com/backend # Backend is my venv
    PassengerAppRoot /var/www/demo.app.com/backend/public # Public is where my code lives

    PassengerPython /usr/bin/python3.8
    PassengerAppType wsgi
    PassengerStartupFile passenger_wsgi.py

    <Directory /var/www/demo.worxmanager.com/backend>
        Allow from all
        Options -MultiViews
    </Directory>
</VirtualHost>

因此，我进入后端文件夹（venv容器）并执行以下命令：

. ./bin/activate

pip3 install -r ./requirements.txt

一切都成功安装。我进入public folder内部，然后进入app.py内部，编写以下代码：

from flask import Flask
#I have more imports and routes, but didn't think they are relevant to my error.

@app.route('/api/user/register', methods=['POST'])
def register():
    return user.register(request)

if __name__ == '__main__':
    app.run()

最后，这是我的passenger_wsgi.py文件：

from app import app as application

当我尝试run或转到demo.app.com时，出现以下错误：

这很奇怪，因为我在requirements和系统本身上都安装了所有venv。
