PATH passed to launch_kernel/Popen() doesn't contain ~/roswell/bin

[ayjayt]

I followed the installation instructions...

So I deleted my original issue, but it's still in the same way: If we're using jupyter hub, we need a way to do per-user path, and that seems hard with the defaults. The lab's inherit their PATH from the hub, which is root. Looking for ways to do it in the config, but then this would be good to add to the docs.

ax that, /etc/environment is NOT loaded by the server launcher.

This is probably cause I'm using hub on systemd but I'm gonna suss out a solution right now anyway.

SOLUTION (hack) Not great,

I changed c.Spawn.cmd in jupyterhub.config (or whatever it's called) to jupyterhub-singleuser to jupyterhub-singleuser-alias and created said jupyterhub-singleuser-alias as a bash script in the same directory as the jupyterhub-singleuser:

#!/bin/bash
export PATH=$PATH:$HOME/.roswell/bin
exec jupyterhub-singleuser

Didn't find any other way to do. Could be wrong. There is no other script that gets sourced before the server is started that allows you to export per user variables. Nothing seems to be executed in a shell by default.

I'm not quite sure why is this a common-lisp-jupyter issue. I don't really use Roswell anymore, but there is an "env" section in the kernel file. https://jupyter-client.readthedocs.io/en/latest/kernels.html#kernel-specs

[ayjayt]

Thanks, I posted here because I followed the instructions here to install it all and still came across the error. (Edit: so i figure the idea would be to make the documentation here clearer so people can use the kernels w/ jupyterhub)

What should we use if not roswell?

That 'env' variable in the kernel file might work, but if we were going to include a note about that in the instructions to make them compatible with jupyterhub, where would it be, and where we would find the kernel file?

You can find the kernel files by doing jupyter-kernelspec list

[ayjayt]

Ok, so I'll test it out... would you be open to a pull request to add to the docs this information for installation so jupyter hub users can also use common-lisp-jupyter with roswell? or should i not bother

Sounds good
