Installation problems

[soegaard]

The documentation on http://khan.github.io/react-components/ says:

In the author's limited experience, it's easiest to clone React Components as a subrepo (assuming Git).

git submodule add https://github.com/Khan/react-components.git react-components

Then simply use CommonJS requires pointing to the components within the subrepo.

var TeX = require('react-components/js/tex.jsx');
React.render(\nabla \cdot E = 4 \pi \rho, domNode);

However:

$ git submodule add https://github.com/Khan/react-components.git react-components
$ cd react-components
$ make

eventually leads to the error:

Error: Cannot find module './react-live-editor/live-editor.jsx' from '/Users/soegaard/Dropbox/GitHub/matematik-app/react-components'

make: *** [docs/preview-bundle.js] Error 1

This page: https://github.com/Khan/react-components shows that react-live-editor is a submodule of react-components so the installation instructions ought to include a note on how to clone react-live-editor.

This command:

 git submodule update --init --recursive

fetched the submodule for me.

Now make gets a little further:

$ make
npm install
npm WARN package.json react-components@0.4.0 license should be a valid SPDX license expression
/

react-components@0.4.0 prepublish /Users/soegaard/Dropbox/GitHub/matematik-app/react-components

pip install -r requirements.txt
make: pip: No such file or directory
make: ** [pydeps] Error 1

This means that I need to install Python...

I only need the TeX component - as mentioned in issue #53 it would be nice to have a simple to use the TeX component without the other components.

Question: Is it necessary to run make? Or can I use the TeX component without?
(the documentation doesn't say whether to run make or not)

You should be able to install react-components from npm and require('react-components/tex'). Not sure why the instructions suggest a submodule…

Thanks for the hint. Eventually I decided to use KaTeX directly.
