Pip Install stuck on "Preparing Wheel metadata..." when trying to install PyQT5

I'm trying to install PyQT5 on my Raspberry Pi and used the command sudo pip3 install pyqt5. But it has been stuck on that for over an hour nowand I'm starting to get frustrated, since it still moves, so it didn't crash or anything. Is there a workaround for that or am I missing something? Thanks in advance

Solution 1:

I had the same problem and got impatient after a few dozen minutes...

Then tried running the command with:
pip3 install --verbose PyQt5
so this way I could always be sure that it didn't crash in the background.
It completed after almost 2 hours. The compilation takes some time...
