找不到'core-js'的類型定義文件

Question

我正在構建一個angular-cli的angular2應用程序。 默認情況下未安裝angular-in-memory-web-api 。

所以我搜索了它並在我的package.json文件中添加了這行"angular-in-memory-web-api": "~0.1.5" 。 並npm install了npm install 。

現在我遇到了這個問題。

ERROR in [default] /home/adil/Code/AngularJS.2/cli-based/mz-doc-app/node_modules/angular-in-memory-web-api/in-memory-backend.service.d.ts:1:0 
Cannot find type definition file for 'core-js'.

請建議一些解決方案？

Answer 1

我通過刪除第一行/// <reference types="core-js" /> of node_modules/angular-in-memory-web-api/in-memory-backend.service.d.ts解決了這個問題。

它不是一個永久的解決方案，而是等待修復（ https://github.com/angular/in-memory-web-api/issues/62 ）

Answer 2

我有一個類似的問題使用webpack。 自版本0.1.10以來，in-mem-web-api有一些重大變化。

https://github.com/angular/in-memory-web-api/blob/master/CHANGELOG.md#0113-2016-10-20

將web api更改為版本0.1.9可以清除我的症狀。 （我是一個有角度的菜鳥，所以很遺憾不知道永久的解決方案）。
