pgadmin4 无法启动应用程序服务器

当我在 manjaro xfce 中打开 pgadmin4 时，会弹出此错误消息：

初始化 pgadmin 4 服务器时发生错误：无法启动应用程序服务器，服务器线程退出。

我确实尝试安装 email_validator

通过使用 pip pip install email_validator 但它仍然向我显示相同的错误

和 pgadmin4 配置似乎是正确的 在此输入图像描述

有时它会奇怪地显示无法打开系统默认 Web 浏览器，并且该错误消息在重新启动后停止，然后在多次尝试打开 pgadmin4 后再次出现

并且仅当 pgadmin4 在后台运行时才会弹出此 Web 浏览器错误，如果我杀死 pgadmin4，然后打开它时会弹出无法启动应用程序服务器错误

在这里找到解决方案https://stackoverflow.com/questions/67610220/pgadmin4-error-modulenotfounderror-no-module-named-email-validator

解决方案是降级 python-flask 和 python-flask-security-too。它们分别不能超过 2.0 和 4.0。
