【问题描述】：
我正在使用本指南使用 Angularfire2 和 firebase 创建一个 Angular 4 项目：
https://github.com/angular/angularfire2
当我安装所有东西并尝试运行“ng serve”时，出现以下错误：
./src/app/app.component.ts 中的错误 未找到模块：错误：无法解析“......”中的“angularfire2”
我看到更多人有这个问题，但我这些答案对我没有帮助。
我使用的是 Angular 4，我的 package.json 看起来像这样：
{
"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",
"@angular/forms": "^4.0.1",
"@angular/http": "^4.0.1",
"@angular/platform-browser": "^4.0.1",

"@angular/router": "^4.0.1",
"core-js": "^2.4.1",
"rxjs": "^5.1.0",
"typescript": "^2.2.2",
"zone.js": "^0.8.4"
},
"devDependencies": {
"@angular/cli": "1.0.0",
"@angular/compiler-cli": "^4.0.0",
"@types/jasmine": "2.5.38",
"@types/node": "~6.0.60",
"codelyzer": "~2.0.0",
"jasmine-core": "~2.5.2",
"jasmine-spec-reporter": "~3.2.0",
"karma": "~1.4.1",
"karma-chrome-launcher": "~2.0.0",
"karma-cli": "~1.0.1",
"karma-jasmine": "~1.1.0",
"karma-jasmine-html-reporter": "^0.2.2",
"karma-coverage-istanbul-reporter": "^0.2.0",
"protractor": "~5.1.0",
"ts-node": "~2.0.0",
"tslint": "~4.5.0",
"typescript": "~2.2.0"
}
}
有人知道为什么会出现此错误以及如何解决它吗？
【问题讨论】：
-
angularfire2在您的package.json中无处可见，因此这可能是问题的一部分。至少安装它：npm install angularfire2 --save -
我确实运行了该安装。但是 angularfire2 没有出现在 package.json 中。
