npm run build拋出錯誤代碼ELIFECYCLE

Question

我已經關注Wes Bos系列的“所有人的ES6”已有一段時間了，我陷入了webpack的一幕。 每當我嘗試在CMD上運行“ npm run build”命令時，都會出現此錯誤：

npm ERR！ 代碼ELIFECYCLE npm ERR！ errno 1 npm錯誤！ webpacktest@1.0.0生成： webpack --progress --watch npm ERR！ 退出狀態1 npm ERR！ npm ERR！ 在webpacktest@1.0.0生成腳本上失敗。 npm ERR！ npm可能不是問題。 上面可能還有其他日志記錄輸出。

在網上搜索了各種解決方案后，我在這里結束了，希望大家能為我提供幫助。 這是運行命令的日志文件：

Answer 1

所以過了一會兒我想出了解決方案，但我不知道它是如何工作的，但是在這里：

我必須更改package.json文件。 最初，它具有這樣的內容（在教程中完全像這樣顯示”

 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) } }) ] }; 

我將整個模塊的輸出更改為此：

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