Unable to run node_modules/.bin/browserifyinc. Ensure you have installed it with npm. (in /Users/labuser/Downloads/betfair_nav_demo-master/app/assets/javascripts/application.js)

I am using Ampersand JS with Rails application. gem 'rails', '4.2.1' gem "browserify-rails", '1.2.0'

I have installed npm install ampersand -g

npm install browserify --save-dev

npm install underscore --save

My Rails app is working without browserify-rails gem.
