Hi list, In my tests for yapf downgrade, I had to build and try to run spyder. I hited a few missing deps when tried to run it on clean and up-to-date Slackware64-15 : python3-textdistance,python3-pydocstyle,QDarkStyle,jupyter-qtconsole,ipython-genutils I've cc'ed the maintainer. If I'm not mistaken, hope that helps. -- Regards, Tonus
