Did you search here on the forum? I think this has come up before.

Yes I searched the forum, but many of those conversation are left in between without proper fix, I also tried steps suggested in those conversation removing node_modules, npm run clean, checking for cocoapods pacakge for macOS but didn't found useful. Can you pls help me?

Try npm 8

After upgrading rpm to latest version and running sudo npm config rm proxy , sudo npm config rm https-proxy I wa sable to build the project but now after starting application blank screen appears.

Anything in console?

Also see the build troubleshootings: Desktop application | Joplin

It clearly shows what the issue is, doesn't it?

Yes, but I am not able to fix it

Check the user running npm has access to the directory. Or just delete it and try again.
