AssertionError: wrong color format 'var(--jp-mirror-editor-variable-color)' while opening jupyter notebook #10
Description
Description
Hi. I tried running jupyter notebook recently and faced with the following issue. I run local jupyter server, try to open any notebook from filesystem and I get 500 : Internal Server Error.
Here are logs from jupyter server.

Reproducer
I installed jupyter with the following steps.
sudo pip3 install virtualenv
virtualenv env
source ./env/bin/activate
pip3 install jupyter
Context
- Operating System and version: Linux Ubuntu 20.04.3
When faced issue for first time tried to google it. Found a recommendation to update pygments to >=2.4.1. Did pip3 install --upgrade pygments. Didn't help. Also tried to update nbconvert. Didn't help as well.
