I have a problem installing a PyQt5 python package. I am in Yocto Linux environment (Hardknott kernel 5.10.35) on the Variscite board (DART-MX8M-PLUS). This is the log when I try to install with pip:
root@imx8mp-var-dart:~# pip install pyqt5

How can it be solved? Thanks in advance!

Answer
Do not bother installing packages natively on the board,
PyQt5 is already supported by Yocto in meta-qt5, link to recipe.
Just add meta-qt5 to your bblayers.conf and :
IMAGE_INSTALL_append = " python3-pyqt5"
