ReferenceError：无法找到变量：在src / app / home / home.component.spec.ts上映射：4 Angular 2

Question

我似乎设置了可错的故障。

错误：

ReferenceError: Can't find variable: Map
at src/app/home/home.component.spec.ts:4

ReferenceError: Can't find variable: Map
at http://localhost:63247/__modules/27.js?1483285680907:80

我设置了js文件，如下所示：

    var wallabyWebpack = require('wallaby-webpack');

var webpackPostprocessor = wallabyWebpack({
  entryPatterns: [
    'src/wallabyTest.js',
    'src/**/*spec.js'
  ],

  module: {
    loaders: [
      {test: /\.css$/, loader: 'raw-loader'},
      {test: /\.html$/, loader: 'raw-loader'},
      {test: /\.js$/, loader: 'angular2-template-loader', exclude: /node_modules/},
      {test: /\.json$/, loader: 'json-loader'},
      {test: /\.styl$/, loaders: ['raw-loader', 'stylus-loader']},
      {test: /\.less$/, loaders: ['raw-loader', 'less-loader']},
      {test: /\.scss$|\.sass$/, loaders: ['raw-loader', 'sass-loader']},
      {test: /\.(jpg|png)$/, loader: 'url-loader?limit=128000'}
    ]
  }
});

var compilerOptions = require('./src/tsconfig.json').compilerOptions;

module.exports = function (wallaby) {

  return {
    files: [
      {pattern: 'src/**/*.ts', load: false},
      {pattern: 'src/**/*.d.ts', ignore: true},
      {pattern: 'src/**/*.css', load: false},
      {pattern: 'src/**/*.html', load: false},
      {pattern: 'src/**/*spec.ts', ignore: true},
      {pattern: 'node_modules/babel-polyfill/browser.js', instrument: false}
    ],

    tests: [
      {pattern: 'src/**/*spec.ts', load: false}
    ],

    testFramework: 'jasmine',

    compilers: {
      '**/*.ts': wallaby.compilers.typeScript(compilerOptions)
    },

    postprocessor: webpackPostprocessor,

    setup: function () {
      window.__moduleBundler.loadTests();
    },

    debug: true
  };
};

项目结构：

我今天刚刚找到这个工具，我很高兴能让它发挥作用。我的项目也在 GitHub Git Hub Link

上

ReferenceError: Can't find variable: Map
    at src/app/home/home.component.spec.ts:4

经过一些研究后，我将以下内容添加到我的wallaby.js文件中，以确保它不使用编译器，因为小袋鼠拥有它。

{pattern: 'node_modules/babel-polyfill/browser.js', instrument: false}

但是我仍然得到同样的错误。

正如@YaroslavAdmin正确提到的那样，重要的一点是src/wallabyTest.ts - 它是从哪里加载polyfill的。您的项目中缺少this file。
