Repro steps

  1. clone this repo.
  2. ng update @angular/core@8 @angular/cli@8 in cli-example folder
  3. ng update @angular/core @angular/cli --next in cli-example folder
  4. add main.playground.ts to files section in tsconfig.app.json in cli-example folder
  5. build and run

Observed Behavior

ERROR in getInternalNameOfClass() called on a non-ES5 class: expected UrlService to have an inner class declaration

Desired Behavior

App builds successfully and playground is available

Any other details that may be useful (optional)

I cloned this repo, tried to find the cause by removing UrlService calls in AppComponent.ts. Once I had removed all references to UrlService I got the same error message but now referring to AppComponent

This problem also occurs with Angular 9.0.1.
It happens sooner if you add ngcc as a postinstall script : it occurs while compiling angular-playground after installing all NPM modules.

Seeing the same issue. Can't use Angular Playground with Angular 9

Same here after update my library to Angular 9.

I've managed to workaround the issue by using this:

"angularCompilerOptions": {
"enableIvy": false, /* for playground */
}
