Jupyter Notebooks

Download and run installer. 

Error: no kernels installed. 

I updated the issue description to better reflect what 'Ground Zero' means.

There are several mentions here and there that nteract ships with a javascript kernel. If that's case, shouldn't it be the default? Or work with nteract --kernel javascript? (Maybe this should be opened as a separate issue?)

From < https://github.com/nteract/nteract/issues/1513 > 

From C:\Program Files\nteract\resources\app.asar.unpacked\node_modules\ijavascript we discover IJavascript  which is presumably the kernel referred to above. From their docs

"IJavascript is a Javascript kernel for the Jupyter notebook "

and

“The IJavascript kernel executes Javascript code inside a Node.js session”

From < https://github.com/n-riesco/ijavascript > 

So our minimum pre-reqs are probably:

• Jupyter << Python 
• Ijavascript << Node.js << npm 

(but why bother with Node when python is already installed from Jupyter?)

install miniconda (60mb dn, 250mb installed)

To get started developing install a python runtime then install nteract itself .

Python runtime 

At least for now, we need the python 3 kernel installed when hacking on nteract:

python3 -m pip install ipykernel 
python3 -m ipykernel install --user

Install nteract itself 

Requires node 6.x and npm 3 .

From < https://doc.esdoc.org/github.com/nteract/nteract/#python-runtime > 

conda install ipykernel
	#installs 16 dependencies including jupyter_core
python -m ipykernel install --user 

From < https://nteract.io/kernels > 

Miniconda folder expands to 310mb.

after this nteract can be started from Anaconda shell prompt, but not from start menu.

Microsoft Visual C++ Compiler for Python 2.7 

Download 

This package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.

From < https://www.microsoft.com/en-us/download/details.aspx?id=44266 > 

Fix for this: (?)
