error on installing enyo-generator

[ha-noi]

npm install -g generator-enyo

gives this

npm WARN deprecated [email protected]: the module is now available as 'css-select'
npm WARN deprecated [email protected]: the module is now available as 'css-what'
npm WARN deprecated [email protected]: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.

npm WARN deprecated [email protected]: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.

How do I fix these errors?
Starting with graceful-fs, I tried this

npm install -g graceful-fs

but

npm ls -g graceful-fs

shows

Why is graceful-fs in [email protected] still at version 3.0.8?

These are only warnings, not errors. Those warnings can be safely ignored for now (unless you are running node >= 7.0). If you would like to submit a tested pull request that updates generator-enyo's dependencies we would welcome it.
