ng add ngx-spinner : The package that you are trying to add does not support schematics

Question

I'm new to Angular.

After executing ng add ngx-spinner, I encountered this error:

The error (ngx-spinner):

The package that you are trying to add does not support schematics. You can try using a different version of the package or contact the package author to add ng-add support.

How can I solve this problem? (How can I add the module manually?)

Answer 1

I uninstalled spinner with

npm uninstall ngx-spinner

and reinstalled with

npm install ngx-spinner --force

Now that's work well.
