Undefined Error: no attribute 'latex_envs'

Followed installation in README.md and encountered the error below. Running jupyter core: 4.6.3. I attempted installation on macOS and Linux and both give the same error, appreciate the help in advance!

$ jupyter nbconvert --to html_with_lenvs MYFILE.ipynb
