Question

I am trying to work through the Angular2 tour of heroes app, and am running into bugs on the Http section of the tutorial.

At first I was getting the error:

For those of you looking at the older articles, try this solution by re-running the application with ng serve.

ng generate service InMemoryData --module=app was a previous solution; however, you get this error:

Unknown option: '--module'

By default, Angular sets the providedIn property inside of the @Injectable decorator. This takes care of registering the service and hence the --module isn't really a practical solution anymore.

In order to restart the angular application, you can run in the CLI... taskkill /IM "node.exe" /F

then, ng serve
