Cant seem to install on ubuntu 18.04

[GurraWeber]

I tried downloading the overlay but I got this

ERROR: Could not find a version that satisfies the requirement PyQtWebEngine (from versions: none)
ERROR: No matching distribution found for PyQtWebEngine

when using python -m pip install PyQtWebEngine.
So I contacted the creator on Reddit and he/she said to use
sudo pip3 install --upgrade pip && sudo pip3 install PyQt5.
That was successful but i got and error that said
WARNING: The directory '/home/gurragg/.cache/pip' or its parent directory is not owned or is not writable by the current user. The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
So I finally used sudo apt install python3-pyqt5 python3-pyqt5 python3-pyqt5.qtwebengine
And it was also successful but with no errors this time. But the problem is that when using discord-overlay it won't start and I cant seem to find the application anywhere. I am using Ubuntu 18.04

Same issues, not sure what's going just commenting here so I can stay updated on this. I know it's a small project pity that Discord won't implement this natively in their actual software for Linux.

The pip command mentions 'If executing pip with sudo...'

Did you attempt the -H flag on sudo?

Hey trigg, just wanted to say I got this working...but at this point I completely forget what I did. You can just close the issue though, thanks for all the hard work.
