我最近安装了 Angular 4 (RC2) 并从简单的快速入门示例中复制了文件。但是当我尝试使用 Webpack 构建项目时，我收到错误消息，指出无法解析 Rxjs：

我已经安装了 Rxjs 5.0.1，我认为这是 Angular 所期望的版本。我想不出还有什么可做的。

new ContextReplacementPlugin( /angular(\\|\/)core(\\|\/)@angular/, path.resolve(__dirname, '../src') ) 适用于 webpack.common.js 中的 webpack

在此配置下工作没有问题：

new webpack.ContextReplacementPlugin(
  /angular(\\|\/)core(\\|\/)@angular/,/angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
  helpers.root('../src'), 
  {} 
),

确保在 helpers.root 上有两个点，而不是一个。('../src')
