Errors initiating Angular Authentication using JWTs and jwtInterceptor

Question

Currently, I am running Angular 1.6.6. and Angular-jwt 0.1.9. I am following the examples from the READ.me file of Angular-jwt as well from the auth0 site here "How can I send the JWT on every request to the server?". The two examples vary slightly. The angular-jwt docs uses jwtOptionsProvider and the auth0 example uses jwtInterceptorProvider in the .config section for the angular controller.

When I run this code the browser console states:

"Failed to instantiate module controllerName due to: Error: [$injector:unpr] 
Unknown provider: jwtInterceptorProvider"

The error is the same for jwtInterceptorProvider and jwtOptionsProvider. Here the code in the angular controller, which is the same as from the docs. I am wanting to just make this code run so that I can understand how to use it:

angular
  .module('app', ['angular-jwt'])
  .config(function Config($httpProvider, jwtOptionsProvider) {
      jwtOptionsProvider.config({
      tokenGetter: ['myService', function(myService) {
      myService.doSomething();
      return localStorage.getItem('id_token');
      }]
 });

   $httpProvider.interceptors.push('jwtInterceptor');
 })

Can someone explain why this error is occurring and how to correct it?
