推荐答案
我在Windows 10 Professional上的pgAdmin 4 1.5遇到了同样的问题.解决方案只是删除由早期版本创建的%appdata%\pgAdmin.在Windows以外的系统上，用户目录中可能有一个pgAdmin目录.当然，删除此选项后，所有会话设置等都将消失.
I had the same problem with pgAdmin 4 1.5 on Windows 10 Professional. The solution was simply to delete %appdata%\pgAdmin which was created by an earlier version. On systems other than Windows, there probably is a pgAdmin directory in your user directory. Of course, all session settings etc. are gone after deleting this.
