Jupyter Scala Missing Kernel

Question

I work on OS X 10.10.5. I am trying to add a Scala core to my Jupyter laptops.

$ jupyter --version 4.0.4 $ conda --version conda 3.17.0 

I downloaded jupyterscala from git, then built Scala 2.11 from sources.

 $ sbt cli/target $ ls -l /Users/davidlaxer/jupyter-scala/cli/target/scala-2.11/ total 224 drwxr-xr-x 4 davidlaxer staff 136 Sep 21 12:39 classes -rw-r--r-- 1 davidlaxer staff 114465 Sep 21 12:39 jupyter-scala-cli_2.11.6-0.2.0-SNAPSHOT.jar $ sudo jupyter kernelspec install scala-2.11/ Password: [InstallKernelSpec] Installed kernelspec in /usr/local/share/jupyter/kernels/ David-Laxers-MacBook-Pro:target davidlaxer$ jupyter kernelspec list Available kernels: ir julia-0.3 matlab_kernel python2 $ ls -l /usr/local/share/jupyter/kernels/ total 224 drwxr-xr-x 4 root wheel 136 Sep 21 12:39 classes -rw-r--r-- 1 root wheel 114465 Sep 21 12:39 jupyter-scala-cli_2.11.6-0.2.0-SNAPSHOT.jar 

Why can't I see the scala2.11 kernel?

No Scala!

To install jupyterscala from sources, you should do something like

 git clone https://github.com/alexarchambault/jupyter-scala.git cd jupyter-scala sbt cli/pack cli/target/pack/bin/jupyter-scala 

Then ipython kernelspec list should display scala211.

For the Scala 2.10 kernel, check the scala -2.10.x branch and make sbt ++ 2.10.5 cli / pack instead of sbt cli / pack. The kernel name is scala210. Please note that to use both cores simultaneously, it is necessary, for example, to clone repos in two different directories.
