Repro steps

• ng new testshell
• set angular 5.1.0 and add @angular/router
• npm install
• ng generate component home
• add router-outlet
• setup routes like that:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';

const appRoutes: Routes = [
  { path: '', component: HomeComponent },
]

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule, RouterModule.forRoot(appRoutes)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Observed behavior

[~/projects/testshell]$ ng generate app-shell --route shell                                                                                       *[master]

I was getting the same error, but I figured out I was entering the wrong command.
What you need to do is either:

ng generate app-shell <app-shell-component-name>  --universal-app=<universal-app-name> --route=<route>

or

ng generate app-shell [ --universal-app <universal-app-name>] [ --route <route>] // notice the brackets
