can't compile the demo app

[maciek252]

Hi,

There is no documentation how to compile the demo app. I wanted to see how to do this. When I issue in sbt "fastOptJS::webpack", I get:

Updating NPM dependencies
[error] Usage: yarn [options]
[error] yarn: error: no such option: --non-interactive
[error] java.lang.RuntimeException: Non-zero exit code: 2

This problem has been mentioned here:
scalacenter/scalajs-bundler#164
But I don't know what the conclusion was and how to fix it here.

OK, the problem was yarn missing from the path, and outdated version of node. Nevertheless, consider adding an information how to compile the demo app.
