Getting fenics shells working within a container on windows

Hello everyone,
I have managed to get fenics to run in a container to which a module is mounted so it can execute python files so far. I followed these instructions: 2. Introduction — FEniCS Containers 1.0 documentation

For running a demo I need fenics_shells as well. I tried following the instructions:
https://fenics-shells.readthedocs.io/en/latest/
Do I need to run this within the container?

git clone https://bitbucket.org/unilucompmech/fenics-shells.git

and then how do I install it?

I also tried to install fenics_shells via

pip3 install git+https://bitbucket.org/unilucompmech/fenics-shells.git

which allows me to import fenics_shells in python, but gives me this error:

I appreciate the help!
