Versions

Windows 7 / Ubuntu 14.04.5 LTS
$ node --version
v8.9.3
$ npm --version
5.5.1
"@angular-devkit/schematics": "~0.0.42"

Repro steps

1. Initialize a new angular cli project, i.e. ng new mycustomproject
2. cd into the created project
3. create a new module including the flat option via angular/cli, i.e.: ng generate module toplevel --flat --module=app

The log given by the failure

vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ ng generate module toplevel --flat --module=app
create src/app/toplevel.module.ts (192 bytes)
update src/app/app.module.ts (389 bytes)
vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ cat src/app/
app.component.css app.component.html app.component.spec.ts app.component.ts app.module.ts toplevel.module.ts
vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ cat src/app/app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { ToplevelModule } from './/toplevel.module';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
ToplevelModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

Desired functionality

vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ ng generate module toplevel --flat --module=app
create src/app/toplevel.module.ts (192 bytes)
update src/app/app.module.ts (389 bytes)
vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ cat src/app/
app.component.css app.component.html app.component.spec.ts app.component.ts app.module.ts toplevel.module.ts
vagrant@vagrant-ubuntu-trusty-64:/projects/mycustomproject$ cat src/app/app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { ToplevelModule } from './toplevel.module';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
ToplevelModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

Mention any other details that might be useful
