How do I install Scala in Jupyter IPython Notebook

问题:

Here's a few links that I went to and did exactly what they said. I don't know what I'm doing wrong.

https://github.com/alexarchambault/jupyter-scala
https://github.com/ipython/ipython/wiki/IPython-kernels-for-other-languages
https://github.com/apache/incubator-toree
http://jcrudy.github.io/blog/html/2013/12/08/introduction_to_iscala.html

None of this is working. It may be some way that my node is configured. I just don't know. Please help. Thanks!

You can use the information given here.

Ensure you have IPython 3 installed. ipython --version should return a value >= 3.0. If it's not the case, a quick way of setting it up consists in installing the Anaconda Python distribution, and then running

$ pip install --upgrade "ipython[all]"

ipython --version should then return a value >= 3.0.

Download the Jupyter Scala binaries for Scala 2.10 (txz or zip) or Scala 2.11 (txz or zip), and unpack them in a safe place. Then run once the jupyter-scala program (or jupyter-scala.bat on Windows) it contains. That will set-up the Jupyter Scala kernel for the current user.

Check that Jupyter/IPython knows about Jupyter Scala by running

$ jupyter kernelspec list

This should print, among others, a line like

scala211

(or scala210 dependending on the Scala version you chose).

Then run either IPython console with

$ ipython console --kernel scala211

and start using the Jupyter Scala kernel straightaway, or run Jupyter Notebook with

$ jupyter notebook

and create Scala 2.11 notebooks by choosing Scala 2.11 in the dropdown in the upper right of the Jupyter Notebook start page.

Note: Since IPython has now been replaced by Jupyter, we replaced ipython in the above commands with jupyter.

The answer for Linux can be found here.

Install Scala. Add these lines to ~/.bashrc

export SCALA_HOME=/usr/local/share/scala export PATH=$PATH:$SCALA_HOME/bin:$PATH Follow these instructions from the GitHub site:

Download and unpack pre-packaged binaries Scala 2.11. Unpack each downloaded archive(s), and, from a console, go to the bin sub-directory of the directory it contains. Then run the following to set-up the corresponding Scala kernel:

./jove-scala --kernel-spec
