I was hoping someone could help me understand why JupyterLab fails to spin up a kernel on my system.
Background
I'm working on macOS High Sierra. I used to have Anaconda installed via the Mac OS installer in the default location in my home folder ($HOME/anaconda). Based on this thread I uninstalled Anaconda.
I reinstalled Anaconda from the Homebrew Cask (placing export PATH=/usr/local/anaconda3/bin:"$PATH" in my .bashrc).
The Problem
Now when I
- run
jupyter-lab, - create a new notebook, and
- select a Python 3 kernel,
the process fails with the following output:
Traceback (most recent call last):

I'd already removed all references to $HOME/anaconda (my old install location) from my environment (.bashrc, .bash_profile), so I can't figure out where the reference is being picked up.
Any suggestions would be greatly appreciated.
