Problem with the compilation AOT

Hi,

I try to use the basic library installation with the Sample Component in a basic application Angular CLI.
ng serve work fine but when you try ng build --prod and try to see in dist folder in web, I have an error r is not a constructor.
I know there is already an issue about it #127 with an answer from @sebastianteres but I don't really understand what to do.
Maybe @sebastianteres you can help too ?

Thank you very much !

Start by reviewing the behavior described for the Sample Component in an Angular CLI application and reproduce it with ng serve, then ng build --prod. Read the guidance in issue #127 and inspect the generated dist output. Done means the production build runs in the browser without the “r is not a constructor” error.
