[ng] Error: Failed to compile entry-point ionic5-alpha-scroll (main as esm5) due to compilation errors:
[ng] node_modules/ionic-angular/umd/module.d.ts:51:22 - error NG6002: Appears in the NgModule.imports of ScrollModule, but could not be resolved to an NgModule class.
[ng] This likely means that the library (ionic-angular) which declares IonicModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
