如何在TypeScript 2.1.4中消除TS2354錯誤消息？

Question

我得到錯誤TS2354：這句法需要進口幫手，但模塊「tslib的」無法找到。在我的webpack 2版本中使用TypeScript 2.1的新importHelpers選項。 該包似乎按預期構建，但錯誤消息令人不安。 任何人都可以指出我在這裏做錯了嗎？或者是與rxjs\Subject.d.ts％的誤差問題（即提到行（Subject.d.ts：9,43）不使用和無辜extends關鍵字）？

ts-loader: Using typescript@2.1.4 and C:Repro\stuff\tsconfig.json

ERROR in C:Repro\stuff\node_modules\rxjs\Subject.d.ts 
(9,43): error TS2354: This syntax requires an imported helper but module 'tslib' cannot be found. 

main.ts

import { Observable } from "rxjs"; 

Observable.timer(3000, 5000) 
    .timeInterval() 
    .subscribe((interval) => console.log(interval)); 

的package.json

{ 
    "name": "stuff", 
    "version": "1.0.0", 
    "scripts": { 
    "build": "webpack" 
    }, 
    "devDependencies": { 
    "@types/core-js": "^0.9.35", 
    "ts-loader": "^1.3.2", 
    "typescript": "^2.1.4", 
    "webpack": "^2.1.0-beta.25" 
    }, 
    "dependencies": { 
    "rxjs": "^5.0.1", 
    "tslib": "^1.2.0" 
    } 
} 

tsconfig.json

{ 
    "compilerOptions": { 
    "module": "commonjs", 
    "importHelpers": true, 
    "target": "es5", 
    "noEmitHelpers": true 
    } 
} 

webpack.config.js

module.exports = { 
    name: 'server', 
    target: 'node', 
    entry: { 'app': './src/main.ts' }, 
    output: { path: './bin/', publicPath: 'bin/', filename: '[name].js' }, 
    externals: { rxjs: 'commonjs rxjs' }, 
    module: { rules: [{ test: /\.ts$/, loader: 'ts-loader' }], }, 
    resolve: { extensions: ['.ts'] } 
};

看起來這是this typescript issue下跟蹤其應固定在打字稿2.1.5
