Question

我正在尝试使用反应热装载机。我在终端中运行“npm start”命令时收到错误。有些人可以告诉我这是什么问题。我正在努力让热装载机工作，但没有在浏览器中启动任何东西。

index.js

import 'babel-polyfill';
import React from 'react';
import ReactDOM from "react-dom";
import {createStore} from 'redux'
import {Provider} from 'react-redux'
import allReducers from './reducers'
import App from './Components/App'
import injectTapEventPlugin from 'react-tap-event-plugin';

const store = createStore(allReducers);
injectTapEventPlugin();
ReactDOM.render(
    <Provider store = {store}>
        <App/>
    </Provider>,
    document.getElementById('root')
);

webpack.config.js文件

var path = require('path');
var webpack = require('webpack');

module.exports = {
    devServer: {
        inline: true,
        contentBase: './src',
        port: 3000
    },

    devtool: 'eval',
    entry: [
        'webpack-dev-server/client?http://localhost:3000',
        'webpack/hot/only-dev-server',
        './dev/js/index.js'
    ],
    module: {
        loaders: [
            {
                test: /\.js$/,
                loaders: ['react-hot', 'babel'],
                include: path.join(__dirname, 'src')
            },
            {
                test: /\.scss/,
                loader: 'style-loader!css-loader!sass-loader'
            }
        ]
    },
    output: {
        path: path.resolve(__dirname, 'src'),
        filename: 'js/bundle.min.js'
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()

    ]
};

通常当我收到这样的错误时，由于无法转换jsx。在你的情况下，我相信这是因为你没有使用babel-loader来完成它。此外，如果您想使用礼物，您需要将它们作为查询参数包含在babel-loader中。我还想排除节点模块以减少转换的时间。

{
  loader: 'babel-loader',
  query: {
     presets:['es2015','react','stage-0'] // Babel presets, I use stage-0 
  },
  test: /\.js$/,
  exclude: /node_modules/,
}

index.js中的解析错误
