@ionic/app-scripts

[andrew1618]

Can't run ionic serve because I get this error:
Looks like @ionic/app-scripts isn't installed in this project
This package is required for this command to work properly. The package
provides a CLI utility, but the ionic-app-scripts binary was not found in
your PATH.

? Install @ionic/app-scripts? Yes

I enter YES and then get this:

Thanks :)

Did you run npm install before doing ionic serve?
