Why doesn't gulp work on OS X?

Question

npm

I write the command:
sudo npm install -g gulp
Gives the following errors:
npm WARN deprecated [email protected]: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated [email protected]: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated [email protected]: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to [email protected]^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
Who can advise what?
