Angular 5: “No provider for ControlContainer”

Question

I have a little web app with Angular 5 and out of a sudden I am getting this strange error message in my browser console:

ncaught Error: Template parse error         


        

Answer 1

In case someone is still having this error while using the Angular CLI, i was only importing the ReactiveFormsModule, then i imported and registered the FormsModule to fix the error. I was serving the app with ng serve when i made changes to the module class and i was still having the error even after importing and registered the FormsModule. To fix the error i had to stop serving and start again in order to recompile the module class.
