无法热更新hot模块

Question

我正在构建一个web应用程序使用的反应-路由器和材料-ui。最近我注意到，react热加载器已经更新，并且在使用ho加载器时出现了一些问题。当我将它与react路由器一起使用时，热加载程序将不能用于子组件。这是我的index.js代码

import React from 'react';
import {render} from 'react-dom';
import { AppContainer } from 'react-hot-loader'
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import { Router, Route, Link, browserHistory,IndexRoute } from 'react-router'
import injectTapEventPlugin from 'react-tap-event-plugin';
import routes from './routes';

injectTapEventPlugin();

const App = () => (
  <MuiThemeProvider>
    <Router history={browserHistory} routes={routes} />
  </MuiThemeProvider>
);

render(<App/>,document.getElementById('app'));

if (module.hot) {
  module.hot.accept('./components/App', () => {
    const NextApp = require('./components/App').default;
    render(
      <AppContainer>
      <MuiThemeProvider>
        <NextApp/>
      </MuiThemeProvider>
      </AppContainer>
      ,
      document.getElementById('app')
    );
  });
}

这里是我的应用程序组件

import React from 'react';
import Home from './Home';
import About from './About/AboutPage.react';
import NavigationBar from './navigation/navigationBar.react';



class App extends React.Component{
   render(){
     return(
       <div>
        <NavigationBar/>
        {this.props.children}
       </div>
     );
   }
}

export default App;

路由文件

import React from 'react';
import {render} from 'react-dom';
import { Router, Route, Link, browserHistory,IndexRoute } from 'react-router'
import App1 from './components/App';
import NavigationBar from './components/navigation/navigationBar.react';
import greetings from './components/Login/greetings';


export default (
     <Route path="/" component={App1}>
       <IndexRoute component={greetings}/>
     </Route>
);

当我对子组件做任何更改时，浏览器控制台会发出警告：

以下模块无法热更新：(完全重新加载所需)这通常是因为模块已经更改(以及它们的父模块)不知道如何热重新加载自己。有关更多细节，请参见 http://webpack.github.io/docs/hot-module-replacement-with-webpack.html 。http://webpack.github.io/docs/hot-module-replacement-with-webpack.html有什么特别的原因，为什么我会得到这个信息，以及如何解决这个问题？

请确保您还在使用react热加载程序的AppContainer组件包装初始呈现。如下所示：

const App = () => (
  <AppContainer>
    <MuiThemeProvider>
      <Router history={browserHistory} routes={routes} />
    </MuiThemeProvider>
  </AppContainer>
);

另外，我没有看到您的webpack配置，所以请确保您在第一个条目中也包含了react-hot-loader/patch，例如：

entry: [
  'react-hot-loader/patch',
  `webpack-dev-server/client?http://localhost:${config.port}`,
  'webpack/hot/only-dev-server',
  './src/index.jsx'
],

如果您也有一个.babelrc文件，请确保将它作为您的插件之一，如下所示：

{
  "presets": [
    "react",
    "es2015",
    "stage-0"
  ],
  "plugins": [
    "react-hot-loader/babel",
    "transform-decorators-legacy"
  ]
}
