I have created Angular project

ng new <projectname>

Then installed Angular fire

ng add @angular/fire

When I compile and run the project

ng serve

I am seeing the below error

My Angular version looks like below. Do I need to degrade the version of Angular?

Angular CLI: 13.3.5
Node: 16.15.0

OS: linux x64

Angular: 13.3.6
... animations, common, compiler, compiler-cli, core, forms

I started having this problem too after updating eslint packages to the latest. In my project, downgrading them to these versions solves the compilation errors:

With @angular/fire being on v.7.3.0:

@eslint/eslintrc --> 1.2.2 (problem started on 1.2.3)

eslint --> 8.14.0 (problem started on 8.15.0)

CodePudding user response：

I had the same problem. I think it's a problem with version 0.20.

I solve it just running:

npm i @firebase/auth@^0.18.3
