当我有这样定义一个简单的组件：addComponentAsRefTo（...）：只有ReactOwner可以参[...]点击菜单项一

class App extends React.Component<{}, {}> { 

constructor() { 
    super(); 
} 

render() { 
    return (
     <MuiThemeProvider muiTheme={muiTheme}> 
      <div> 
       <Drawer open={true}> 
        <MenuItem primaryText="123" /> 
       </Drawer> 

      </div> 
     </MuiThemeProvider> 
     ); 
    } 
}

当我点击MenuItem，我得到这两个错误，并且菜单项获得灰色背景。

这是的package.json：

是否有反应或与材料的UI做什么？问题的解决方法是什么？

https://github.com/JedWatson/react-select/issues/606也许这会有所帮助。 –

你在应用程序的某处调用injectTapEventPlugin（）函数吗？ –

我发现了这个问题。

似乎出于某种原因，我在index.html（来自node_modules）中包括React和ReactDOM，但也将其作为依赖项包含在package.json中。

<script src="./node_modules/react/dist/react.js"></script> 
    <script src="./node_modules/react-dom/dist/react-dom.js"></script>

我从index.html的去除上面的两行，也从我的WebPack配置文件中的这些行：

externals: { 

"react": "React", 

"react-dom": "ReactDOM" 

}

问题的解决方法是什么？

其中一个react-包取决于直接的反应，从而把自己的react版本造成两人反应得到加载版本。在node_modules及其子文件夹

修复

查找一个文件夹react确定包惹的祸。

'npm ls react'给了我' - react @ 15.4.1'，所以我不认为没有多个React版本就有问题...... –
