make Julia show up on JupyterLab

I have installed Julia (on Linux) at a location, say /a/b/c, along with IJulia, the kernel package required to make Julia show up on JupyterLab. I would like this to be for a multi-user mode (I understand they will not have ability to install/maintain packages)

When I set $HOME to /a/b/c, JupyterLab shows the Julia kernel and everything seems to work. This is not a viable solution for multiple reasons.

I tried a few different options, so far to no avail:
- Created a softlink: ln -s /a/b/c/.julia /home/guru/.julia
- Set env variable JULIA_PROJECT to /a/b/c/.julia then to /a/b/c/.julia/environments/v1.0/
- Also tried setting JULIA_PKGDIR but this seems to be obsolete anyway

What is the right way to have /a/b/c/.julia show up for everyone when they launch JupyterLab?

I recommend adding Jupyter Lab to Julia via Conda.jl and just using this added version.

using Conda
Conda.add("jupyterlab")

Now run from the console:

~/.julia/packages/Conda/hsaaN/deps/usr/bin/jupyter lab

There are many other options so comment if you need something different.

It seems that JupyterLab cannot find julia command. Because it is not in your PATH.

You can try the following command to create a link for your julia executable in a directory which is in PATH. The usual directory to do that is /usr/local/bin.

sudo ln -s /a/b/c/bin/julia /usr/local/bin/julia

This should work for all users. Note that /usr/local/bin might not exist in some Linux distributions. If you have such a distribution, run echo $PATH in Linux command line to see which directories are in path.

Another solution would be to add julia's bin directory to PATH for all users. 

sudo echo "export PATH=$PATH:/a/b/c/bin" >> /etc/profile

I would go for the first solution.

Try the instructions here: it seems to require re-installing IJulia with the ENV["jupyter"] environment variable first set properly.
