I tried reinstall Octoprint with
~/oprint/bin/pip install --force-reinstall OctoPrint==1.8.0 --no-cache-dir
but, error happen
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
awesome-slugify 1.6.5 requires Unidecode<0.05,>=0.04.14, but you have unidecode 1.3.4 which is incompatible.

WARNING: There was an error checking the latest version of pip.
I'm having the same issue. My upgrade from 1.7.3 to 1.8.1 "worked" but then octoprint failed to start with all sorts of python errors. So I'm trying to re-install steps but it's failing due to unidecode and slugify. How can I remove the octolapse plugin if octoprint isn't running? I guess I'll try to uninstall slugify and see what happens.
edit heh, answered my own question ... used pip to remove octolapse and was able to reinstall octoprint 1.8.1.
