Question

我正在使用angular2构建angular-cli应用程序。默认情况下未安装angular-in-memory-web-api。

所以我搜索了它并在我的"angular-in-memory-web-api": "~0.1.5"文件中添加了这一行package.json。并npm install。

现在我遇到了这个问题。

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'.

请建议一些解决方案？

Answer 1

我通过删除/// <reference types="core-js" />

的第一行node_modules/angular-in-memory-web-api/in-memory-backend.service.d.ts解决了这个问题

它不是永久解决方案，而是等待修复（https://github.com/angular/in-memory-web-api/issues/62）

Answer 2

我使用webpack遇到了类似的问题。自版本0.1.10以来，in-mem-web-api有一些重大变化。

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

将web api更改为版本0.1.9可以清除我的症状。（我是一个有角度的菜鸟，所以很遗憾不知道永久的解决方案。）

找不到＆＃39; core-js＆＃39;
