Error SampleModule' imported by the module 'AppModule' on Generate Build With Angular 5

I updated the packages from this lib to the new version of Angular 5, but consuming the library in an application generates the following error.

`Unexpected value 'SampleModule' imported by the module 'AppModule'. Please add a @NgModule annotation.`
