No such kernel named lua

No such kernel named lua

[guysv]

first of all: macos support is work in proress (i.e. yet to exist).

just fresh-installed it on my mac, unlike your it launched, but crashed after the first command.

Regarding how I know jupyter, i'd say this bug happened because jupyter couldn't discover ilua's configuration files properly.
I have two requests to you:

1. ls -laR /usr/local/share/jupyter/
2. check if ipython, jupyter's primary shell, is working.

Thank you very much for your reply and input.
I used to have ilua installed on my old mac, and it would launch and run just fine.

1. At first this did not work using the default directory. Seemed to work after providing the installed path.
   a) ~ % ls -laR /usr/local/share/jupyter ls: /usr/local/share/jupyter: No such file or directory
   b) '~ % ls -laR /Users/zccafa3/Library/Python/3.7/share/jupyter

I use multiple versions of pycharm. Typically I use homebrew to manage package installations, not pip, as it better handles this and related pathing issues (in my experience). As brew install ilua was not available, I used pip3 install ilua to install the package. This required me to overcome some pathing issues with a .zshrc file;
export PATH="${PATH}:/Users/zccafa3/Library/Python/3.7/bin" export PYTHONPATH="${PYTHONPATH}:/Users/zccafa3/Library/Python/3.7/bin"
However, Lua 5.2.4 has been installed to the default location. I suspect it has something to do with this.

2. This runs fine.

Jupyter looks in a different data path by default on Mac OS. See: https://docs.jupyter.org/en/latest/use/jupyter-directories.html#id2

If your kernel lives at $path/kernels/lua/kernel.json, then you can set the environment variable JUPYTER_DATA_DIR=$path to get ilua working.

A long way down the road (sorry life got in the way for a while) and a fresh install later, I am able to use ilua again. Unfortunately, some other (unrelated) issues started to crop up with my mac, which lead to a whipe and fresh install, so I was not (and cannot currently) reproduce this issue. Closing this out (but of course re-open if you would like the record for yourselves). Thanks
