未找到网页输入模块(按教程)

建立 this tutorial ReactJS )

一步一步地实现它,就像它被告知的那样,但我最终遇到了这个错误(当我尝试构建一切时)

未找到输入模块中的错误:错误:无法解决 C:\Users\temp1\Documents\Learn\ReactJS\playaroundapp\index。html'输入 “C:\Users\temp1\Documents\Learn\ReactJS\playaround” “C:\Users\temp1\Documents\Learn\ReactJS\playaround” (相对路径:.) 使用描述文件后:C:\Users\temp1\Documents\Learn\ReactJS\playaround\package.json (相对路径:.) 无扩展名 字段“browser”不包含有效的别名配置 C: \Users\temp1\Documents\Learn\ReactJS\playaroundapp\index.html 不存在 .js 字段“browser”不包含有效的别名配置 不存在 字段“browser”不包含有效的别名配置 C: \Users\temp1\Documents\Learn\ReactJS\playaroundapp\index.html.json 作为目录

矿 webpack.config.js :

/** webpack required stuff */
var HTMLWebpackPlugin = require('html-webpack-plugin');

var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
        template: __dirname + 'app/index.html',
        filename: 'index.html',
        inject: 'body',
        minify: {
            removeComments: true,
            collapseWhitespace: true,
            removeAttributeQuotes: true
        },
        chunksSortMode: 'dependency'
    });

/** thing which traces stuff and transforms in teh better way with babel(?) */
module.exports = {
    entry: __dirname + '/app/index.js',
    module:{
        loaders:[
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader'
            }
        ]
    },
    output:{
        filename: 'transformed.js',
        path: __dirname + '/build'
    },
    stats: {
            colors: true,
            modules: true,
            reasons: true,
            errorDetails: true
    },
    plugins: [HTMLWebpackPluginConfig]     
};
