Jupyter Kernel Error (Installation using Old Method 2)

[MarsSongco]

I tried installing Maxima-Jupyter using old method 2 (Maxima-Jupyter loadable source installation) and I got this message indicating that I have installed maxima-jupyter successfully.

However, opening jupyter notebook and choosing maxima as the kernel gives out a kernel error like this:

The whole error log reads:

Is this an indication of a wrong path setting or is this an indication of an error somewhere in my installation process? Thank you!

If you are using Windows the installation is more difficult because of the cffi and static-vectors dependency in common-lisp-jupyter. I would go try to get common-lisp-jupyter working first. Also, I haven't used the old installation method for a very long time.
