Question

使用react-router和material-ui构建Web应用程序。我最近注意到反应热装载机已经更新并且在使用材料-u的ho装载器时遇到了一些问题。当我使用它与反应路由器时，热的加载器不适用于儿童组件。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')
    );
  });
}

这是我的App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;

路线档案

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>
);

当我对子组件进行任何更改时，浏览器控制台会发出警告说明以下模块无法热更新:(需要完全重新加载）这通常是因为已经改变的模块（及其父母）不知道如何热重新加载自己。有关详细信息，请参阅http://webpack.github.io/docs/hot-module-replacement-with-webpack.html。我得到这个以及如何解决这个问题的任何特殊原因？

确保您还使用react-hot-loader的AppContainer组件包装初始渲染。像这样：

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

另外，我没有看到你的webpack配置，所以请确保你的第一个条目也包括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'
],

如果您还有一个.babelrc文件，请确保将其作为您的插件之一包含在内：

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

React模块无法进行热更新
