我是React和React Hot Loader的新手 . 我有一个Symfony 2.7应用程序，并开始使用webpack并做出反应 .

一般来说一切正常，但是当我想使用Hot Reloading时，我收到错误：

Ignored an update to unaccepted module ./app/Resources/js/app.js -> 0
[HMR] The following modules couldn't be hot updated: (They would need a full reload!)
[HMR]  - ./app/Resources/js/app.js

我在这里遗漏任何基本的东西 . 我很新，所以它可能是一个简单的答案 . 非常感谢

这是我的基本代码：

的package.json

"dependencies": {
    "babel-core": "^6.25.0",
    "babel-loader": "^7.1.1",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-0": "^6.24.1",
    "babel-preset-stage-2": "^6.24.1",
    "react": "^15.6.1",
    "react-dom": "^15.6.1",
    "react-hot-loader": "^1.3.1",
    "webpack-dev-server": "^2.6.1"
  }

app.js

import React from 'react';
import ReactDOM from 'react-dom';
// import ReactHotLoader from 'react-hot-loader';
import Component from './component.js';

// const element = ;
ReactDOM.render(
    <h1>Hello, world app </h1>
    ,
    document.getElementById('app')
);

webpack.config.js：

var path = require('path');
var webpack = require('webpack');
var node_modules_dir = path.join(__dirname, 'node_modules');

var config = {
    entry: [
        'webpack-dev-server/client?http://127.0.0.1:3000',
        'webpack/hot/only-dev-server',
        './app/Resources/js/app.js',
    ],
    output: {
        path: path.join(__dirname, 'web/dist'),
        filename: 'bundle.js',
        publicPath: 'http://127.0.0.1:3000/static/'
    },

    plugins: [
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoEmitOnErrorsPlugin(),

    ],
    module: {
        loaders: [
            {
                test: /\.js?$/,
                include: path.join(__dirname, 'app/Resources/js'),
                loader: "babel-loader",
                query: {
                        presets:['react']
                }
            }
        ]
    }
};

module.exports = config;
