我正在为我的 rails 4 应用程序使用react-rails 。使用反应模块的唯一方法是通过这种方法。一切都很好，没有问题。一直以来，我都在使用 chrome 版本 47.0.2526.106（64 位）。

使用任何其他浏览器，我得到React is not defined.

奇怪的是，如果我//= require react在application.js其中删除了消息，但我肯定会要求 React 两次，这会产生其他问题，因为 react 是必需components.js的React = require('react');

简而言之，我正在使用react-rails gemand npm react。我只需要使用npm版本的react和react-rails的格式'<%= react_component() %>

关于为什么 chrome 没有任何问题而不是其他问题（firefox，safari）的任何解决方案。我没有尝试过资源管理器。

应用程序.js：

//= require jquery
//= require jquery_ujs
//= require foundation
//= require moment
//= require ckeditor/init
//= require components
//= require react-rails-hot-loader
//= require_tree .

...

组件.js：

//= require_self
//= require react_ujs

React = require('react');
ReactDOM = require('react-dom');
LinkedStateMixin = require('react-addons-linked-state-mixin');

...

错误堆栈：

//error stack:
(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({"/Users/sylar/Sites/rails/simple-app/app/assets/javascripts/components/_stream_0.js":[function(require,module,exports){
var Dashboard = React.createClass({ 
  displayName: "Dashboard",

  render: function () {
    return React.createElement(
      "div",
      null,
      "Hi"
    );
  }

});
module.exports = Dashboard;
},{}]},{},["/Users/sylar/Sites/rails/simple-app/app/assets/javascripts/components/_stream_0.js"]);
