Hi guys,
I have on my laptop the python installation 3.8 and newly I installed newest
version 3.10 as well on my laptop.
Now I have two IDLEs for both of the installations.
When I rund some *.py file, having PyQt5 module, on the 3.8 version, it works
as before without any problems.
But whenn I run the same file on IDLE with 3.10 installation, it crashes and
says that PyQt5 is not known.
I tried to install this package with"pip install pyqt5" or with "py -3 -m pip
install pyqt5", it brings lots of error messages (long long) as the lines below
(they are only the beginning of the messages):
==================================================

==============================================
What is wrong with my installations.
How can I get all the packages available in 3.8 version also available for 3.10
version without any new installation in 3.10 for each all already existing
packages?
Thanks a lot in advance for you contributions.
Mohsen
