角度误差：找不到模块'firebase/app'

Question

我正在尝试在这里关注谷歌的Codelab： 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，我收到以下错误：

node_modules/@angular/fire/database/interfaces.d.ts(2,26) 中的错误： 错误 TS2307：找不到模块"火碱/应用程序"。

火力基地 --版本 6.4.0

我尝试在堆栈溢出上搜索并尝试一些不起作用的事情：

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

或者尝试使用最新的火力基地：

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

也不起作用。

我真的很感激任何帮助， 一

Answer 1

AngularFire 已移至@angular/fire。在你的package.json中，你有"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

Answer 3

我正在登录并且正在使用nuxt.js，它给了我以下错误：

Cannot find module 'firebase / compat / app' 17:26:42 Require stack: - /home/script/nuxt-firebase-auth/node_modules/@nuxtjs/firebase/lib/module.js

由于您使用的是 angular 和 I nuxt，因此仅从依赖项的版本更改

"@ nuxtjs / firebase": "^ 8.0.0"

自

"@ nuxtjs / firebase": "^ 7.6.1"
