Angular 6 - can't resolve all parameters for AppComponent

Question

I am trying to build an application with Angular 6 and I am still setting everything up. But it seems there is something wrong with the dependency injection in my app.

Answer 1

I also got this issue but setting emitDecoratorMetadata": true in tsconfig solve the issue. Remember to restart the server.

tsconfig.spec.json

"compilerOptions": { "emitDecoratorMetadata": true, "outDir": "./out-tsc/spec",
