That sound right. It is strange because PyPI has a PyQt6-Charts-Qt6 wheel for all
platforms. Please try to install that manually with "<path to venv>/bin/python3 -m pip
install PyQt6-Charts-Qt6". At the moment I have no idea, why this failed.
I tried to install 22.7 and got this error message:
ERROR: Could not find a version that satisfies the requirement PyQt6-Charts-Qt6>=6.3.0 (from PyQt6-Charts>=6.2.0->eric-ide) (from versions: none)
ERROR: No matching distribution found for PyQt6-Charts-Qt6>=6.3.0 (from PyQt6-Charts>=6.2.0->eric-ide)
Also im am missing in the directory bin the file eric7_post_install and each file beginning whith eric_
