We get the same error. This error we have because we are using Angular 4. But when upgrading ng2-formio to RC1, the error is a bit different:

ERROR in Unexpected value 'FormioModule in C:/.../node_modules/ng2-formio/dist/index.d.ts' imported by the module 'AppModule in C:/.../src/app/app.module.ts'. Please add a @NgModule annotation.

Could anyone help please? Is there any quick temporal workaround at least?

I found a quick solution.

1. in app.modules.ts change FormioModule import to import locally:
   import { FormioModule } from './my-formio';

2. and then create new file, my-formio.ts:
   import { NgModule } from '@angular/core';
   import { CommonModule } from '@angular/common';
   import { FormioComponent } from 'ng2-formio/dist/formio.component';
   import { FormioAlertsComponent, FormioAlerts } from 'ng2-formio/dist/formio.alerts';
   import { FormioLoader, FormioLoaderComponent } from 'ng2-formio/dist/formio.loader';
   @NgModule({
   imports: [
   CommonModule
   ],
   declarations: [
   FormioComponent,
   FormioLoaderComponent,
   FormioAlertsComponent
   ],
   exports: [
   FormioComponent,
   FormioLoaderComponent,
   FormioAlertsComponent
   ],
   providers: [
   FormioLoader,
   FormioAlerts
   ]
   })
   export class FormioModule {}
   export { FormioAppConfig } from 'ng2-formio/dist/formio.config';
   export { FormioLoader } from 'ng2-formio/dist/formio.loader';

Should be fixed with RC5.
