angular官网教程第7个HTTP，找不到angular-in-memory-web-api

Question

我在学习angula中文网第七个教程http时，有一个api接口找不到，遍寻staroverflow跟google无果...

package.json

  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",

    "e2e": "ng e2e"
  },

  "dependencies": {
    "@angular/common": "^2.4.0",
    "@angular/compiler": "^2.4.0",

  }
}

这是报错的画面

操作台报错画面

Answer 1

npm i --save angular2-in-memory-web-api

Answer 2

自问自答

npm i angular-in-memory-web-api

缺少了这个就安装这个，参考链接

Answer 3

英文版文档中有：npm install angular-in-memory-web-api --save
Docs地址：https://next.angular.io/tutor...
而且中文版文档最后一篇写出来的有问题，在线演示也是，会有以下错误信息

ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'slice' of undefined
TypeError: Cannot read property 'slice' of undefined

而英文版的演示可以运行，应该是中文版文档并未及时维护

Answer 4

我也是遇到了同样的问题，上面说的我都测试了
我是两个都下载完成了之后，就好了

Answer 5

按照前面的回答吗没有解决问题 ，按照这个http://blog.csdn.net/redzealo...地址改写了package.json后重新安装解决了问题

Answer 6

上面的没有一个能解决的，，最后把angular-in-memory-web-api和angular2-in-memory-web-api全部删掉。使用cnpm install angular-in-memory-web-api --save 安装成功。之后没有再报错。后面的人可以试试
