Bug reference: 17934 Logged by: Tony Marston Email address: tony@tonymarston.net PostgreSQL version: 15.3 Operating system: Windows 10 Description:
I have just upgraded from version 15.2 to 15.3, but when I try to run pgAdmin there is a long time delay before it comes up with the message: "The pgAdmin 4 server could not be contacted". Below that it shows full details of the error which ends with the following:
import psutil File "E:\Program Files\PostgreSQL\15\pgAdmin 4\python\lib\site-packages\psutil\__init__.py", line 241, in <module> raise ImportError(msg) ImportError: version conflict: 'E:\\Program Files\\PostgreSQL\\15\\pgAdmin 4\\python\\lib\\site-packages\\psutil\\_psutil_windows.cp310-win_amd64.pyd' C extension module was built for another version of psutil (5.9.3 instead of 5.9.5); you may try to 'pip uninstall psutil', manually remove E:\Program Files\PostgreSQL\15\pgAdmin 4\python\lib\site-packages\psutil\_psutil_windows.cp310-win_amd64.pyd or clean the virtual env somehow, then reinstall
