Gulp modules won't run?

Question

gulp.js

Good evening. I cloned a project that contains Gulp, with written modules for building less, etc. But when I opened the project in WebStorm and opened the Gulp panel, I got a message: Failed to list tasks. I ran the following commands:
1. npm install -g gulp
2. npm install gulp
But in general it didn't help... By clicking on the details link, the following was revealed:
Failed to list gulp tasks in smarttv-main\gulpfile.js: process finished with exit code 1 (a non-zero exit code means an error)

I don't understand what is the reason for this. Please help me understand.
