python - WINdows 7 上 PgAdmin 4 的“启动应用程序服务器时出错。无法启动应用程序服务器”

问题描述

对于尝试在 Windows 7 上启动 PgAdmin4 时收到的上述错误消息，我已经尝试了 Stackoverflow 上建议的所有可能解决方案。

例如以管理员身份运行，将默认浏览器更改为 chrome/firefox/internet explorer，清除所有临时文件和转储文件，确保没有预安装其他版本的 PgAdmin，系统环境变量中没有 PYTHONPATH 环境变量，在 services.msc 中重新启动 postgresql 服务ETC

我已经在不同的 PC 上成功安装了 PgAdmin 几次，从未遇到任何问题。我也附上了 PgAdmin4 的转储
