推荐答案

今天我遇到了同样的问题:

The same problem happened to me today:

这就是我的解决方法:

1)使用文本编辑器打开 c:\ Program Files \ pgAdmin 4 \ v1 \ web 下的 config_distro.py 文件. >文件夹.将 SERVER_MODE 的值从 True 更改为 False ，然后保存更改. (我已经以管理员身份运行Notepad ++，以便能够保存在此受保护的文件夹中.)

1) Use a text editor to open the config_distro.py file under the c:\Program Files\pgAdmin 4\v1\web folder. Change the value for SERVER_MODE from True to False, then save the change. (I have run Notepad++ as an Administrator, in order to be able to save in this protected folder.)

2)转到文件夹 c:\ Users \ your_name \ AppData \ Roaming \ pgAdmin ，并确保其中没有任何内容(删除所有文件，因为它们是临时，将在启动 pgAdmin )

2) Go to folder c:\Users\your_name\AppData\Roaming\pgAdmin and make sure there is nothing there (delete all the files, as they are temporary and will be restored after starting pgAdmin)

3)开始 pgAdmin

4)这次，您会看到一个白色的盒子，至少在我运行缓慢的笔记本电脑上，这个盒子大约需要20秒. (您可能会短暂看到原始错误消息，但不用担心).

4) This time you will see a white box that sits - at least, on my slow laptop - about 20 seconds. (You may briefly see the original error message, but do not worry).

5)同时，将创建运行该应用程序所需的临时文件.

5) Meanwhile, the temporary files - required for running the application - are created.

6):临时文件处理结束后，应用程序将按预期方式启动.

6) Once the temporary files process is over, the application starts as expected.
