Property 'performance' is missing in type 'FirebaseApp' but required in type 'App'

Question

I seem to be getting this error when I try to run a fresh install of Angular 7.2 and Firebase:

ERROR in node_modules/@angular/fire/firebase.app.module.d.ts(17,22): error TS2420: Class 'FirebaseApp' incorrectly implements interface 'App'.
  Property 'performance' is missing in type 'FirebaseApp' but required in type 'App'.

Tried switching between different versions of @angular/fire and firebase, but didn't manage to find a working combination.

Current package.json :

{
  "name": "my-app",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",

  },

    "tslint": "~5.11.0",
    "typescript": "~3.2.2",
    "webpack-cli": "^3.1.0"
  }
}

Has anyone encountered this error? Google doesn't seem to find anything related to the performance property, there are only similar errors, but not the same ones. Any ideas?

Answer 1

我也收到此错误。 似乎是最新版本。 firebase的{​​{1}}中的一个已损坏。

将依赖关系更改为 5.11.0 解决了此问题。

重要提示：请勿不要使用任何5.10.0或~版本。前缀

Answer 2

通过将Firebase的版本指定为“ 5.0.4”而不是“ ^ 5.0.4”来解决此问题。

Answer 3

通过命令将Firebase的版本更改为5.10.1

npm install --save firebase@5.10.1

对我有用。

Answer 4

问题：

node_modules/@angular/fire/firebase.app.module.d.ts：17：22中的错误-错误 TS2420：类“ FirebaseApp”错误地实现了接口“ App”。
“ FirebaseApp”类型缺少属性“性能”，但在“ App”类型中必需。

17个导出声明类FirebaseApp实现app.App {

node_modules / firebase / index.d.ts：1217：5 1217 performance（）：firebase.performance.Performance; 此处声明为“性能”。

解决方案：

通过以下命令将firebase的版本更改为5.10.1：

npm install --save firebase@5.10.1

肯定可以。
