[Error] Generic type 'ActionReducerMap' requires 3 type argument(s)

thisisgit opened this issue 7 years ago · 6 comments

Hi, I'm new to ngrx and getting the error below when trying use ActionReducerMap. I checked the version of @ngrx/store and is 4.0.0 and also tried to uninstall and install to check if there's issue while installing, but still seeing the same error (Generic type 'ActionReducerMap' requires 3 type argument(s)).

So I tried checking what's in ActionReducerMap (models.d.ts), and I see the error below. I tried changing ... extends Action = Action> to ...extends Action> and the errors disappear in models.d.ts but in ActionReducerMap, now it says Generic type 'ActionReducerMap' requires 2 type argument(s).

Answer 2 · 2017-07-24T11:23:41.000Z

I managed to get rid of all those compile errors by replacing all ... extends Action = Action> to ...extends Action>, and when typing ActionReduceMap or ActionReduce, I used ActionReduce<State,Action>, not ActionReduce<State>. Is it only me who's having this issue?

You need to update your version of TypeScript to 2.4.1

Answer 4 · 2017-08-20T23:33:10.000Z

I still see this

@angular/* : 4.2.0
@ngrx/core: 1.2.0
@ngrx/store: 4.0.3
Typescript : 2.4.1
node : 7.0.0
npm : 3.10.8

@afirdousi what version of RxJS are you on? You should have at least TypeScript 2.4.2, RxJS 5.4.2 and remove @ngrx/core from your project to use V4.x

Answer 6 · 2017-08-29T20:12:34.000Z

What solved this for me:
Uninstall all ngrx dependencies first: npm uninstall @ngrx/store @ngrx/effects @ngrx/core --save
Then re-install the latest dependencies WITHOUT core: npm install --save @ngrx/store @ngrx/effects
