ReactJs CreateClass不是函数

根据文档，您需要获取npm
create react class软件包。从项目文件路径的命令行，您需要执行

npm install create-react-class--save

var React = require('react');//You need this npm package to do createReactClassvar createReactClass = require('create-react-class');    module.exports=createReactClass({ render:function(){     return(         <div>  <h1> the list  </h1>         </div>        ) }

您还需要React DOM来呈现这样的组件：

npm install react react-domvar ReactDOM = require('react-dom');ReactDOM.render(<GroceryItemList/>,app);
