no problem. just to clarify what i was talking about, i'm not implying you to change the folder names, but their references in the angular.json file.
So the problem is that in the angular.json file, ion-rangeslider is not capitalized correctly. This is not a problem in windows as dir paths are not case-sensitive. But in linux this is a problem. Go through your node_modules folder after yarn and make sure ion-rangeslider (and all paths) are correctly capitalized.
Yes, and that was obviously not it. So the problem is that in the angular.json file, ion-rangeslider is not capitalized correctly.

Did you figure this out? I'm having the same problem and when i go and look for the files, they're all there
