I do have python-pyqtwebengine installed on my system. I am running arch linux. I a lso have python on my system but i already tried removing PyQt5 and pyqtwebengine using my system’s pip and reinstalling and in both ways i always had this same missing QtWebEngine error.

I saw many errors like this on the issues here and they always end up like that’s not a spyder problem, but maybe we need better installing instructions?

This is not issue with Spyder but with Anaconda. Please report it here:

I have solved my issue. Sorry for the multiple comments, but I want to help anyone else who may run into this. I think it was a Ubuntu libraries problem. After sudo apt-get install libxss1 to fix the ImportError, I got another one that was basically identical: ImportError: libEGL.so.1: cannot open shared object file: No such file or directory It took a little digging to find the right package this time, but I did sudo apt-get install libegl1-mesa, and Spyder worked after that! I’m using WSL 2 here, so I did have to fiddle with my X display settings, but that’s a different issue. Anyway, I hope this helps anyone who may come looking, and saves the Spyder developers from more work in explaining.
