Question

我有以下代码：

<MenuItem primaryText="home" containerElement={<Link to="/" />} />

但是它没有像其他主题/线程中所解释的那样，其中MenuItem在这里讨论Material UI Menu using routes。一旦我将menuElement prop添加到MenuItem，我就会遇到这个异常：

Uncaught Error: 
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. 
You likely forgot to export your component from the file it's defined in.
Check the render method of `EnhancedButton`.

看起来不再有效（需要找到更改日志。）

为了解决这个问题，我做了npm install react-router-dom --save并使用了以下代码段：

import React, { Component } from 'react';
import { NavLink } from 'react-router-dom'
import Menu from 'material-ui/Menu';
import MenuItem from 'material-ui/MenuItem';
import Drawer from 'material-ui/Drawer'

    <Drawer
         docked={false}
         open={this.state.open}
         onRequestChange={(open) => this.setState({open})}>
         <MenuItem onTouchTap={() => {this.handleClose()}} >
              <NavLink to="/">Home </NavLink>
         </MenuItem>
         <MenuItem onTouchTap={() => {this.handleClose() }} >
              <NavLink to="/about"> About Us </NavLink>
         </MenuItem>
    </Drawer>

React material-ui MenuItem containerElement无法正常工作
