Hi, I clone the project, run 'npm install' and after I run 'ionic serve' but the compiler return this error message:

This sample project does not function. What exactly are you looking to accomplish? Perhaps I can update it if needed.

thanks @jamesdeantv this was a feedback. Now I've created a new Ionic project with Videogular and it works. Thanks
