Fails to build from AUR

[Prayag2]

I was trying to install it from the AUR but got the following error:

 -> error making: python-colr

It seems like it's facing some issues installing python-colr package. I have reported this in the python-colr AUR page too (https://aur.archlinux.org/packages/python-colr#comment-860172).

I have found a workaround until this is fixed:

• 0st
  git clone python-colr and kde-material-you-colors
• 1st
  go to the python-colr folder and run makepkg -o
  o: no build, it will run till prepare () included but not build ()
• 2nd
  Open the setup.py file that throws the error and add .strip('\n') at the end of both lines that end with f.read()
  This removes all the newline characters from the descriptions that could cause the error
• 3rd
  run makepkg -sei
  s: install dependencies
  e: no extract
  i: install with pacman
• 4th
  go to the kde-material-you-colors folder and run makepkg -i

Yeah, there is an open pull request in Colr repo see welbornprod/colr#10 that seems fixes this problem.

But is weird it that It works on my system™

Maybe you do not have the latest setuptools? Idk...

[luisbocanegra]

Yeah that is! I have the setuptools v59 installed from official packages and has been flagged out-of-date since 2022-03-21 while setuptools from pip is now on v62. Maybe you have installed setuptools with pip as root before or are using the git version of it?
