Document how to make evcxr a rust jupyter kernel on Mac OS X

[Congee]

I confirm evcxr_jupyter works on my mac box. But I spent more time than expected to make it work because I couldn't find any relevant documentation.

Below is what should be added to the docs.

$ brew install zmq
$ evcxr_jupyter --install
Writing /Users/CC/Library/Application Support/jupyter/kernels/rust/kernel.json
Installation complete
$ jupyter  kernelspec install ~/Library/Application\ Support/jupyter/kernels/rust
[InstallKernelSpec] Removing existing kernelspec in /usr/local/share/jupyter/kernels/rust
[InstallKernelSpec] Installed kernelspec rust in /usr/local/share/jupyter/kernels/rust

Alternatively, if you

mv /Users/$USER/Library/Application\ Support/jupyter/kernels/rust /Users/$USER/Library/Jupyter/kernels/

then it is not necessary to run the jupyter kernelspec install command.

This suggests to me that the evcxr_jupyter --install command should be installing to a different directory on OS X? I'm using Jupyter 4.4.0.

Edit. Perhaps the above only works because I already had Julia kernel support installed at that location.

FYI, I am using jupyter 4.4.0 and Mac OS X 10.11.6

Thanks for filing this bug. I think this is fixed by #22. Feel free to reopen, or send a PR if you think there's anything else missing.

Thanks to @Congee, this helped me to configure rust jupyter for jupyter notebook.

@davidlattimore, still a bug. Instructions described here https://github.com/google/evcxr/blob/main/evcxr_jupyter/README.md
were not enough to make jupyter notebook work with Rust.
