尽管已安装并配置了 python 路径，但 wsgi + apache 中的 ModuleNotFoundError

Question

所以我将所有要求安装到虚拟环境中，但是仍然显示此错误

我的 apache 配置文件看起来像这样

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.

我已经研究了几个小时来解决这个问题，但我找不到一个可行的方法。我尝试了virutalenvs，非virtualenvs，一切。

我昨天也遇到了同样的问题。我通过完全删除 virtualenv 然后重新创建它并在执行 pip3 install -r requirements.txt 之前安装了 django 来解决它，它确实有效。
