Gulp not installing

I am trying to clone the FCC site and run it locally on my mac. I’m doing this so that I can keep track of my activity on Github. I found leonfeng’s post in the FCC forum and followed it, but I am able to install everything except Gulp. I run the installation and it seems like it installed but after checking it I only get this message which I included on the screenshot. Has anyone encountered this?

Here is the link to leonfeng’s post:

Try this node_modules/.bin/gulp -v

I was able to get the ver. 3.9.1

Thank you
