Question

我很反应和webpack。每次我运行该程序，我得到这个问题，我无法解决。我完成了之前的问题并尝试了他们的解决方案，但问题仍然存在。

webpack

module.exports = {
    entry: './src/App.js',
    output: {
        path: __dirname,
        filename: 'app.js',
},
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel',
                query: {
                    presets: ['es2015', 'stage-0', 'react']
                },
            },
            {
                test: /\.css$/,
                loader: 'style-loader!css-loader',
            },
        ],
    },
};

App.js

import React from 'react';
import ReactDOM from 'react-dom';

var CommentBox = React.createClass({
    render: function () {
        return (
            <div className="CommentBox">
                Hello, world!I am Comment Box.
            </div>
        );
    }
});

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


package.json

我复制了你的文件并尝试安装它。

我遇到的是＆＃39; npm install＆＃39;仅安装依赖项并且不安装devDependencies。它有时会发生......而且可能就是这种情况。

你能试试吗

npm install -g cordova

你也错过了一个包，babel-preset-stage-0

npm install --only=dev

然后尝试再次运行webpack？
