TS2304:在Webpack/Angular 2中找不到名称“Description”

Question

我已经广泛地搜索了这个问题，但没有找到任何修复它的方法。我正在尝试使用webpack来运行单个jasmine测试。我试图在Angular网站上遵循教程，但它...不是真的正确或完整。

null

var webpack = require('webpack');
var helpers = require('./helpers');

module.exports = {
  devtool: 'inline-source-map',

  resolve: {
    extensions: ['.ts', '.js']
  },

  module: {
    rules: [
      {
        test: /\.ts$/,
        loaders: [
          {
            loader: 'awesome-typescript-loader',
            options: { configFileName: helpers.root('tsconfig.json') }
          } , 'angular2-template-loader'
        ]
      },
      {
        test: /\.html$/,
        loader: 'html-loader'

      },
      {
        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
        loader: 'null-loader'
      },
      {
        test: /\.css$/,
        exclude: helpers.root('src', 'app'),
        loader: 'null-loader'
      },
      {
        test: /\.css$/,
        include: helpers.root('src', 'app'),
        loader: 'raw-loader'
      }
    ]
  },

  plugins: [
    new webpack.ContextReplacementPlugin(
      // The (\\|\/) piece accounts for path separators in *nix and Windows
      /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
      helpers.root('./src'), // location of your src
      {} // a map of your routes
    )
  ]
}

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "es2015",
      "dom"
    ],
    "module": "es2015",
    "moduleResolution": "node",
    "sourceMap": true,
    "target": "es5"
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ],
  "compileOnSave": false,
  "atom": {
    "rewriteTsconfig": false
  }
}

呃...我找到了。正如我在文章中所说，我使用的是typescript 2.0.9，但@types/jasmine的最新版本使用的是keyof，这是typescript 2.1...：/

我将@types/jasmine还原到2.5.41，一切正常。
