Cannot find module 'angular-in-memory-web-api'

在《Angular官方教程第七课HTTP》调试示例出现

Cannot find module 'angular-in-memory-web-api'

分析问题

估计是缺少

angular-in-memory-web-api

依赖包，到工程根目录下的

node_modules

文件夹下去寻找

angular-in-memory-web-api

没有找到。

解决问题

查看工程根目录下的

package.json

，没有添加

angular-in-memory-web-api

，于是在”dependencies”下添加

"angular-in-memory-web-api": "^0.3.2"

{
"name": "angular-tour-of-heroes",
"version": "0.0.0",
"license": "MIT",
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
"private": true,
"dependencies": {
"@angular/animations": "^4.0.0",
"@angular/common": "^4.0.0",
"@angular/compiler": "^4.0.0",
"@angular/core": "^4.0.0",
"@angular/forms": "^4.0.0",
"@angular/http": "^4.0.0",
"@angular/platform-browser": "^4.0.0",
"@angular/platform-browser-dynamic": "^4.0.0",
"@angular/router": "^4.0.0",
"core-js": "^2.4.1",
"rxjs": "^5.1.0",
"zone.js": "^0.8.4",
},
"devDependencies": {
"@angular/cli": "1.1.1",
"@angular/compiler-cli": "^4.0.0",
"@angular/language-service": "^4.0.0",
"@types/jasmine": "2.5.45",
"@types/node": "~6.0.60",
"codelyzer": "~3.0.1",
"jasmine-core": "~2.6.2",
"jasmine-spec-reporter": "~4.1.0",
"karma": "~1.7.0",
"karma-chrome-launcher": "~2.1.1",
"karma-cli": "~1.0.1",
"karma-jasmine": "~1.1.0",
"karma-jasmine-html-reporter": "^0.2.2",
"karma-coverage-istanbul-reporter": "^1.2.1",
"protractor": "~5.1.2",
"ts-node": "~3.0.4",
"tslint": "~5.3.2",
"typescript": "~2.3.3"
}
}

然后在项目根目录下执行

cnpm install

安装

angular-in-memory-web-api

依赖。

然后重新执行

npm start

。
