[SOLVED] TypeError: attrib() got an unexpected keyword argument 'factory'

I run Ubuntu 18.04.4 and I've downloaded the 2.8.0 tarball. When I try to run it , I get the errors below:

Hi @radub7 ! You likely need to upgrade attrs. Try running pip3 install --user --upgrade attrs.

Yes, that was the problem! Thank you @shlomif

I'm reopening this issue due to the first tip in this essay - the one about fixing user problems permanently.

Hello,
I hit this problem on Centos 7 , I don't think I can update python-attrs on EPEL 7 , because EL7 is near EOL (more or less in 2 years) and people don't want hear about it .
So can we workaround PySolFC-2.15.0 to not use factory and just use it on EL 7 ? or should I go back to PySolFC-2.14.0 on EPEL 7 ?

Thank you

huch , I just checked and PySolFC-2.8.0-2.el7 already requires python-attrs 18.2.0

This looks like it's been fixed with the attrs version requirement, so closing this for now.
