Question

我正在尝试遵循Google的代码实验室： https://codelabs.developers.google.com/codelabs/firebase-cloud-functions-angular/index.html?index=..%2F..index#5

当我尝试构建项目：ng build --prod时，出现以下错误：

node_modules/@angular/fire/database/interfaces.d.ts（2,26）中的错误：错误TS2307：找不到模块“ firebase / app”。

package.json

webpack                           4.29.0

firebase --version 6.4.0

我尝试搜索stackoverflow并尝试了一些无效的方法：

npm uninstall firebase
npm install firebase@4.8.0
rm -rf node_modules
npm install

，或尝试使用最新的Firebase：

npm uninstall firebase
npm install firebase
rm -rf node_modules
npm install

也不起作用。

我真的会寻求帮助，

Answer 1

AngularFire已移至@angular/fire。在package.json中，您有"angularfire2": "^5.0.0-rc.6.0"（旧版本）和"@angular/fire": "^5.1.1"

阅读Angularfire文档，并确保使用兼容版本

Answer 2

您需要安装package.json文件中定义的firebase依赖项：

例如：npm install firebase@4.3.0

角度错误：找不到模块“ firebase / app”
