Build failed with node version 6.9.1 and npm 4.1.1. Downgrade npm to version 3.10.10 and get working now.

npm install npm@3.10.10 -g

Notice devEngines specified in package.json as follows:

  "devEngines": {
    "node": "4.x || 6.x",
    "npm": "2.x || 3.x"
  },

I downgrade npm every time I need to build a new version of draft-js. Nice job, FB.
