I’m developing an web app using Ionic 3. I need to use ng2-vs-for library as virtual scroll component because native virtual scroll don’t works well. In development mode the build process goes fine. But when I do a production build, I get this error:
ionic-app-script task: "build"
[13:08:32] Error: Error encountered resolving symbol values statically. Could not resolve ng2-vs-for relative to

I think it must be related to AOT compiling.
How could I solve this error?
