An empty output file when running Examples

Hi there,
I have installed Gulp recently, when I try to run any input example from examples folder, I get an empty output file without any error notification,
I used this syntax

gulp <example1. gin> file. got

hope I can find help
Thanks in advance

If you type exactly what you’ve put above then you’ll get an error message:

no such file or directory: example1.

as there are no spaces after the . in the file names. If the spaces are a typo in your message, then the problem is because you haven’t put the gulp executable in your path. See the (or even execute it) to see how things should work.
