我一直在关注 Wes Bos 系列“所有人的 ES6”有一段时间了，但我被一个 webpack 剧集困住了。每当我尝试在我的 CMD 上运行“npm run build”命令时，我都会收到此错误：
npm 错误！代码 ELIFECYCLE npm ERR！错误号 1 npm 错误号！[email protected] 构建：
webpack --progress --watchnpm ERR！退出状态 1 npm ERR！npm 错误！[email protected] 构建脚本失败。npm 错误！这可能不是 npm 的问题。上面可能有额外的日志输出。
在网上搜索了各种解决方案后，我最终在这里希望你们能帮助我。这是运行命令的日志文件：

我不得不更改我的 package.json 文件。起初它有这样的内容（它在教程中完全像这样显示”
const webpack = require('webpack');
const nodeEnv = process.env.NODE_ENV || 'production';
module.exports = {
devtool: 'source-map',
entry: {
filename: './app.js'
},
output: {
filename: '_build/bundle.js'
},
module: {
loaders: [{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: ['es2015-native-modules']
}
}]
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
},
output: {
comments: false
},
sourceMap: true
}),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify(nodeEnv)
}
})
]
};我将整个模块导出更改为：
module.exports = {
entry: ['./app.js'],
output: {
path: __dirname + '/build',
filename: 'bundle.js'
}
