Hello,
I use a pretty Python 3 application found on Pypi, named youtube-downloader which needs the Python module PySide2, and PySide2 requires the Shiboken2 module.
The two packages pyside2 (5.15.1-1) and python-shiboken2 (5.15.1-2) from the officials repositories are installed on my box, and youtube-downloader works perfectly, but pip list doesn’t see these two modules. pip check returns:
youtube-downloader 0.6.0 requires pyside2, which is not installed.
My python-pip (20.2-1) package is also from the officials repositories
Using pip list --path /usr/lib/python3.8/site-packages > piplistglobal.txt and pamac list | grep -E -i 'python-|PySide2' > pamaclist.txt, and then comparing the two files, I have scored the python3 packages from the official’s repositories not listed by pip list. Only a small part of them is not recognized by pip:
pyside2 5.15.1-1 extra 53,2 Mo *
python-dbus 1.2.16-1 extra 556,2 ko *
python-dbus-common 1.2.16-1 extra 8,9 Mo *
python-shiboken2 5.15.1-2 extra 437,9 ko *
But all is working fine… import PySide2 or import shiboken2 work perfectly even (even they are very case-sensitive)
