Try to add ReactiveFormsModule in your component as well   import   FormGroup  FormArray  FormBuilder            Validators ReactiveFormsModule    from   angular forms

I have solved it by importing FormModule in a shared module and importing the shared module in all other modules  My case is the FormModule is used in multiple modules

I think that this is an old error that you tried to fix by importing random things in your module and now the code does not compile anymore  while you don t pay attention to the shell output  the browser reload  and you still get the same error   Your module should be     NgModule     imports        CommonModule      FormsModule      ReactiveFormsModule        declarations        ContactComponent        export class ContactModule

I had the same problem and I solved the problem in another way  without import ReactiveFormsModule  You may be but this block in   ngOnInt         userForm   new FormGroup           name  new FormControl            email  new FormControl            adresse  new FormGroup               rue  new FormControl                ville  new FormControl                cp  new FormControl

Don t use userForm   new FormGroup    Use form   new FormGroup   instead    And in the form use  lt form  formGroup   form  gt      lt  form gt   It works for me with angular 6

import the ReactiveForms Module to your components module

For those still struggling with the error  make sure that you also import ReactiveFormsModule in your component  s module ts file  meaning that you will import your ReactiveFormsModule in your app module ts and also in your mycomponent module ts file
