Windows 7上PgAdmin 4的“启动应用程序服务器时发生错误无法启动应用程序服务器”

如何解决Windows 7上PgAdmin 4的“启动应用程序服务器时发生错误无法启动应用程序服务器”

在尝试在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，在系统环境变量中没有PYTHONPATH环境变量，在services.msc中重启了postgresql服务，等等。 / p>

我已经在不同的PC上成功安装了PgAdmin数次，并且从未遇到任何问题。我还要附加PgAdmin4的转储文件

解决方法

问题已解决。我安装了Windows 10，一切开始无缝运行。我不知道是什么引起了问题。
