ReactDom未定义

Question

我正在使用React与Webpack和Babel.我收到运行时错误:

未捕获的ReferenceError:未定义ReactDom

我的反应版本是:

"devDependencies": {
   "phantomjs-polyfill": "0.0.2",
   "react-addons-test-utils": "^0.14.8"
 },    
 "dependencies": {
   "react": "^0.14.7",
   "react-dom": "^0.14.7"
 },

我的代码是:

import React from 'react';
import ReactDOM from 'react-dom';
import Main from './components/main';

ReactDom.render(<Main />, document.getElementById('root'));

我究竟做错了什么？

Answer 1

你有,ReactDOM但你没有ReactDom(区分大小写)

ReactDOM.render(<Main />, document.getElementById('root'));
