downgrading to version 0.18.2 works OK
pip3 install --no-dependencies jupyterthemes==0.18.2

The solution in #218 works for me. Just replace notebook.less with the converted version in site-packages/jupyterthemes/layout. On MacOS (homebrew), site-packages is located in /usr/local/lib/python3.6/

Would someone mind upgrading to version 0.18.8 to see if this is fixed? And could you report your results back here? Thanks!

pip install --upgrade jupyterthemes

Hello @dunovank - yes this issue is now fixed in version 0.18.8, no errors when I switch themes. Many thanks.
