npm run build throws error code ELIFECYCLE
提问by Kirdeika
I've been following Wes Bos series "ES6 for everyone" for a while now and I got stuck on a webpack episode. Whenever I try to run "npm run build" command on my CMD i get this error:
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 CMD 上运行“npm run build”命令时，我都会收到此错误：
npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] build:
webpack --progress --watchnpm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] build script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm 错误！代码 ELIFECYCLE npm ERR！错误号 1 npm 错误号！[email protected] 构建：
webpack --progress --watchnpm 错误！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。
After searching for various solutions on the web I end up here in hope you guys can help me. Here is the log file of the run command:

So after a while I figured out the solution, I just don't know how it worked, but here:
所以过了一段时间我想出了解决方案，我只是不知道它是如何工作的，但在这里：
I had to change my package.json file. At first it had content like this (it was shown in the tutorial exactly like this"
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)
}
})
]
};And I changed whole module exports to this:
我将整个模块导出更改为：
module.exports = {
entry: ['./app.js'],
output: {
path: __dirname + '/build',
filename: 'bundle.js'
}
}
