我该怎么办？..

Answer 1

可能是 python 版本不匹配，或者您没有正确地将 python 路径添加到 appache.conf 。 去查看这篇文章以了解有关此错误的更多信息 ->>> link

Answer 2

以下解决方案可能适合您 如果您的服务器使用旧的 python 版本（例如 3.6）并且您更新到了 3.11，则可能会发生这种情况。这些是我推荐的以下步骤

1. 激活virtual env conda环境（如果你使用anaconda更新python）。
2. 在该环境中运行“pip install mod_wsgi”
3. 调整 /apache2/etc/loadmodule.conf 以从 myvirtualenv 内部加载新的 mod_wsgi
4. 重新启动httpd
