I installed gulp(globally) and it looks like it worked because it ran this code:
├── tildify@0.2.0 ├── interpret@0.3.5 ├── pretty-hrtime@0.2.1 ├── deprecated@0.0
If you are on Mac run use root privilege
sudo npm install gulp-cli --global
To check if it's installed run
gulp -v
CLI version: 2.2.0 (The output)
Local version: Unknown
