Using pipenv's virtualenv as a kernel in JupyterHub

Run python -m ipykernel install --user --name=<kernel-name> in pipenv-enabled shell.

pipenv install --dev ipykernel
pipenv shell
python -m ipykernel install --user --name=<kernel-name>

This command will generate kernelspec as ~/.local/share/jupyter/kernels/kernel-name

Why this works?

JupyterHub just runs your jupyter notebook process as the same procedure as using jupyter notebook solely.
