I'm new to Ionic. I was following the Ionic documentation "get started", created a project sample named "super". The problem is that when I run the command line ionic serve in the project directory, it threw an error Error: Cannot find module '@ionic/app-scripts'
app-scripts currently compatible with node 6 and 7. İf you installed node 8, then please uninstall and install node 6 stable version. This solved error and now i can use ionic 3, angular 4 . Take care!
