Webpack Angular2 无法从小部件库中找到 .ts 文件

Question

我正在尝试将组件库集成到angular2/webpack/typescript项目中。

该库已经转译为 javascript，但是当它被加载时，看起来 webpack 正在寻找 .ts 文件。这是我正在使用的 webpack 配置：

module.exports = {
  ......
  entry: {
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'main': './src/main.ts'
  },
  resolve: {
    extensions: ['', '.ts', '.js']
  },
  .....
  module: {
    preLoaders: [
        {test: /.js$/, loader: 'source-map-loader', exclude: [helpers.root('node_modules/rxjs')]}
    ],
    loaders: [
      {test: /.ts$/, loader: 'awesome-typescript-loader', exclude: [/.(spec|e2e).ts$/]} ,
      {test: /.json$/, loader: 'json-loader'},
      {test: /.css$/, loader: 'raw-loader'},
      {test: /.html$/, loader: 'raw-loader', exclude: [helpers.root('src/index.html')]}
    ]
  },
  plugins: [
    new ForkCheckerPlugin(),
    new webpack.optimize.OccurenceOrderPlugin(true),
    new webpack.optimize.CommonsChunkPlugin({name: ['main', 'vendor', 'polyfills'], minChunks: Infinity}),
    new CopyWebpackPlugin([{from: 'src/assets', to: 'assets'}]),
    new HtmlWebpackPlugin({template: 'src/index.html', chunksSortMode: 'none'}),
    new webpack.DefinePlugin({'ENV': JSON.stringify(METADATA.ENV), 'HMR': HMR})
  ]  
};

我正在 webpack 开发服务器中运行该应用程序。以下是错误消息：

./~/primeng/components/selectbutton/selectbutton.js
Cannot find source file 'selectbutton.ts': Error: Cannot resolve 'file' or 'directory' ./selectbutton.ts in C:data14-03angular2-webpack-starternode_modulesprimengcomponentsselectbutton

Answer 1

我能够通过更新 webpack 配置以从 primeng 中排除源映射来解决此错误：

module.exports = {
  ....
  module: {
    preLoaders: [
      ...
      {
        test: /.js$/,
        loader: 'source-map-loader',
        exclude: [
          helpers.root('node_modules/primeng')
        ]
      }
    ]
    ...
  }
  ...
};
