Temporary workaround was to install

pip3 install setuptools==45

bumping MarkupSafe to version 1.1 in requirements.txt also works, PR?

Same here, MarkupSafe=1.1 works.
I also needed to pip install python-magic-bin==0.4.14 for a successful server start (got a ImportError: failed to find libmagic. Check your installation upon using python run.py).

Working environment.yml:

name: flame-env
