在 apache/wsgi 下运行 python/poetry flask 应用程序时遇到问题

如何解决在 apache/wsgi 下运行 python/poetry flask 应用程序时遇到问题

我用诗写了一个烧瓶应用程序，想在 apache 和 wsgi 的控制下运行它。我花了几个小时搜索文档和试验，我学到了很多，但仍然没有弄清楚。这是一连串的打击：

当我直接从诗歌中的命令行运行该应用程序时，它可以工作：

 python3 ./otproject/otpflask/src/run.py
 * Serving Flask app 'teacher' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production Wsgi server instead.
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 141-706-196
^Crpsalas@otproject:~/mydev/development$

根据诗歌，我的venv在这里：

$ poetry env info

VirtualEnv
Python:         3.8.10
Implementation: cpython
Path:           /home/rpsalas/.cache/pypoetry/virtualenvs/otproject-Yy_WWjvb-py3.8
Valid:          True

System
Platform: linux
OS:       posix
Python:   /usr

然后我配置我的apache mod_wsgi如下

<VirtualHost *:80>
    WsgiDaemonProcess test python-home=/home/rpsalas/.cache/pypoetry/virtualenvs/otproject-Yy_WWjvb-py3.8
    WsgiProcessGroup test
    WsgiApplicationGroup %{GLOBAL}
    WsgiScriptAlias /test /var/www/test/test.wsgi
    <Directory /var/www/test/src/>
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

wsgi python 脚本 test.wsgi 如下所示：

#!/usr/bin/env python
from otproject.otpflask.teacher import app as application

但是当我重新启动 apache 服务时，它严重失败了：

Fatal Python error: init_fs_encoding: Failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'
