npm run build抛出错误代码ELIFECYCLE

Question

我已经关注Wes Bos系列的“所有人的ES6”已有一段时间了，我陷入了webpack的一幕。 每当我尝试在CMD上运行“ npm run build”命令时，都会出现此错误：

npm ERR！ 代码ELIFECYCLE npm ERR！ errno 1 npm错误！ webpacktest@1.0.0生成： webpack --progress --watch npm ERR！ 退出状态1 npm ERR！ npm ERR！ 在webpacktest@1.0.0生成脚本上失败。 npm ERR！ npm可能不是问题。 上面可能还有其他日志记录输出。

在网上搜索了各种解决方案后，我在这里结束了，希望大家能为我提供帮助。 这是运行命令的日志文件：

所以过了一会儿我想出了解决方案，但我不知道它是如何工作的，但是在这里：

我必须更改package.json文件。 最初，它具有这样的内容（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) } }) ] }; 

我将整个模块的输出更改为此：

 module.exports = { entry: ['./app.js'], output: { path: __dirname + '/build', filename: 'bundle.js' } }
