I'm trying to build a project (https://www.learmoreseekmore.com/2021/07/ngrx-v12-an-angular-state-management-using-ngrx-data.html) that uses ngRx/data. I have the following version of Angular installed

$ ng --version

     _                      _                 ____ _     ___
    / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
   / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
  / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
 /_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
                |___/

I have repeatedly removed my node_modules and package-lock.json files, but after running

npm i

and then

ng serve

I keep getting the errors

What is the appropriate version of Angular I should be using to support ngrx/data?

CodePudding user response：

You should keep both versions the same.

If you're using angular 11, you should use ngrx 11.
