NullInjectorError: No provider for ActivatedRoute

Question

when I execute my angular application locally, this error occurred suddenly even without doing any code changes while the same code base can be run in a separate machine with the same configuration.

• node version:v16.17.0

ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(AppModule)[ActivatedRoute -> ActivatedRoute -> ActivatedRoute]: NullInjectorError: No provider for ActivatedRoute!

Answer 1

Try to add the following import in AppModule file

imports: [ 
    RouterModule.forRoot([]),
    ...
  ],

To import RouterModule you should do something like this:

import { RouterModule } from '@angular/router';
