问题描述：

我创建一个角4项目，Angularfire2和使用本指南火力点：无法解析“angularfire2” - 角4

当我安装了一切，我尝试运行“NG服务”以下错误apears：在./src/app/app.component.ts 模块

错误未找到：错误：无法解决 'angularfire2' '......'

我看到更多的人有这个问题，但我的答案d没有帮助我。

我使用角4，和我的package.json看起来是这样的：

{ 
"name": "xxxxxxx", 
"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": "^4.0.1", 
"@angular/common": "^4.0.1", 
"@angular/compiler": "^4.0.1", 
"@angular/compiler-cli": "^4.0.1", 
"@angular/core": "^4.0.1",

}, 
"devDependencies": {

"@types/jasmine": "2.5.38", 
"@types/node": "~6.0.60",

"karma-coverage-istanbul-reporter": "^0.2.0", 
"protractor": "~5.1.0", 
"ts-node": "~2.0.0", 
"tslint": "~4.5.0", 
"typescript": "~2.2.0" 
} 
}

有谁看到为什么这个错误出现，我该如何解决呢？

'angularfire2'是无处在'package.json'待观察，所以这就是问题的一部分可能。至少安装它：'npm install angularfire2 --save' – cartant

我确实运行了这个安装。但是angularfire2并没有显示在package.json中。 – boikersoik

答

我认为是因为Firebase本身没有正确安装。这为我做：

NPM安装火力angularfire2 --save
