npm 运行生成引发错误代码 ELIFECYCLE

Question

我一直在关注Wes Bos系列"ES6 for everyone"一段时间了，我被困在了webpack剧集上。每当我尝试在我的CMD上运行"npm运行构建"命令时，我都会收到此错误：

代码 elifecycle npm 错误！ errno 1 npm 错误！ webpacktest@1.0.0 构建：webpack --progress --watchnpm 错误！退出状态 1 npm 错误！ 呵呵！在 webpacktest@1.0.0 生成脚本中失败。呵呵！这 对于 npm 来说可能不是问题。可能存在其他日志记录 上面的输出。

在网上搜索各种解决方案后，我最终来到这里，希望你们能帮助我。下面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，我只是不知道它是如何工作的，但在这里：

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'
}
}
