Question

操作系统：Windows 10 Pro
NPM版本：3.8.6

因此，我尝试使用npm build构建项目但未生成项目构建输出文件夹，并生成以下错误日志：

＆＃13;

我的package.json内容如下：

＆＃13;

  "scripts": {
    "build:webpack": "NODE_ENV=production webpack --config webpack.config.prod.js",
    "build": "npm run clean && npm run build:webpack",
    "test": "NODE_ENV=production mocha './tests/**/*.spec.js' --compilers js:babel-core/register",
    "clean": "rimraf dist",
    "start": "node devServer.js"
  },

＆＃13;

我的webpack.config.prod.js内容如下：

＆＃13;

var path = require('path');
var webpack = require('webpack');

module.exports = {
  devtool: 'source-map',
  entry: [

    './client/reduxstagram'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.DefinePlugin({
      'process.env': {
        'NODE_ENV': "'production'"
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      compressor: {
        warnings: false
      }
    })
  ],
  module: {
    loaders: [
    // js
    {
      test: /\.js$/,
      loaders: ['babel'],
      include: path.join(__dirname, 'client')
    },
    // CSS
    { 
      test: /\.styl$/, 
      include: path.join(__dirname, 'client'),
      loader: 'style-loader!css-loader!stylus-loader'
    }
    ]
  }
};

＆＃13;

这是什么问题？

Answer 1

通过更改以下问题解决了问题：

"build:webpack": "NODE_ENV=production webpack --config webpack.config.prod.js",

到

"build:webpack": "set NODE_ENV=production && webpack --config webpack.config.prod.js",

Answer 2

我遇到了同样的问题，有时与代码无关。

有时将“main.js”和“app.js”文件放在项目的“src”文件夹中！

文件“main.js”被复制到文件夹“src”中，在同一个文件夹中是子文件夹“components”“app.js”

那是我问题的解决方案！

＆＃39; npm build＆＃39;不会在Windows 10 Pro上生成项目构建
