Use IJavaScript kernel inside GraalVM with Jupyter frontend. about ipolyglot

[JakobEdding]

--spec-path-full alone didn't do the trick for me. I needed to add /path/to/graalvm/Contents/Home/jre/languages/js/bin to my PATH as well for the ijskernel binary to be invoked correctly at kernel session initialization.

(Plus I'm using a conda environment with Python 2.7 so I was able to omit the --python=python2.7 flag.)

works on Ubuntu and MacOS now.
for MacOS, the installatiomn guidline provided in the repo

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install pkg-config node zeromq
sudo easy_install pip
pip install --upgrade pyzmq jupyter
npm install -g ijavascript
ijsinstall

can be followed with a few exceptions:
npm install should be run using --python=python2.7;
ijsinstall must be invoked using its full system path, because it's not found inside GraalVM otherwise;
as @jonashering discovered correctly 🎊, ijsiinstall must be used with the --spec-path=full option

What does ijsiinstall do by the way? Does it only copy static files for the web component from Jupyter?

[niconomaa]

imo it basically does some jupyter version checking, sets up the kernel specification and then install the kernel by invoking jupyter kernelspec install
