使用Angular2优化webpack时的副作用

Question

我正在尝试执行

webpack --optimize-minimize

在我的Angular2 SPA上并收到以下错误。

WARNING in ./wwwroot/dist/bundle.js from UglifyJs
Side effects in initialization of unused variable OPERATORS [./~/angular2/src/co
re/change_detection/parser/lexer.js:422,0]

我的webpack.config.js就是这个

module.exports = {
  "entry": "./Angular/boot",
  "output": {
    "filename": "./wwwroot/dist/bundle.js"
  },
  "resolve": {  
    "extensions": [ '', '.js', '.ts' ]
  },
  "module": {
    "loaders": [
      {
        "test": /\.ts/,
        "loaders": [ 'ts-loader' ],
        "exclude": /node_modules/
      }
    ]
  }
};

当运行页面时，我得到“超出最大调用堆栈大小”，因此有一些循环引用继续使用缩小的javascript。

帮助表示感谢，非常感谢
