After the migration of my app from Angular 4^ to Angular 6 (newest version) I got a very weird error in my Auth service.
Specific, the angular2-jwt package is causing a killer error when I try to "serve" or "build" the app in production environment. In the other hand, the same code runs perfectly well on "dev" environment.
OS -> MacOS 10.13.6
The error I got when execute ng serve --configuration production:
ERROR in : Error: Internal error: unknown identifier [{"filePath":"/Users/paulo/Projects/eleo-usuario/node_modules/angular2-jwt/angular2-jwt.d.ts","name":"AuthHttp","members":[]},{"filePath":"/Users/paulo/Projects/eleo-usuario/node_modules/@angular/common/common.d.ts","name":"LocationStrategy","members":[]}]

NOTE: This library is now at version 2 and is published on npm as @auth0/angular-jwt. If you're looking for the pre-v1.0 version of this library, it can be found in the pre-v1.0 branch and on npm as angular2-jwt. @auth0/angular-jwt v2 is to be used with Angular v6+ and RxJS v6+. For Angular v4.3 to v5+, use @auth0/angular-jwt v1
you need install @auth0/angular-jwt to use with Angular v6+
