React_on_rails: Cannot find module "react"

[woniesong92]

I want to use an npm module called react-select

The module includes the following:

var React = require('react');
var ReactDOM = require('react-dom');
var Input = require('react-input-autosize');
var classes = require('classnames');
var Value = require('./Value');
var SingleValue = require('./SingleValue');
var Option = require('./Option');

Then, react_on_rails crashes when I try import Select from 'react-select', complaining Uncaught Error: Cannot find module "react".

More logs:

You probably have not properly installed React.
