Release a new version (with bumped graceful-fs dependency)

[ChALkeR]

graceful-fs versions lower than v4 reevaluate native fs module source, which is not supported.
You should update your graceful-fs dependency to v4 or later.

It is already updated in the current master, but no new version has been released yet, so the current version still uses old graceful-fs.

Tracking issue: nodejs/node#5213.

Indeed. It triggers a warning upon npm install less:

npm WARN deprecated [email protected]: graceful-fs version 3 and before will fail on newer node releases. Please update to graceful-fs@^4.0.0 as soon as possible.

That's because of isaacs/node-graceful-fs#58

Looks like it was done in 2.6.1: https://github.com/less/less.js/blob/v2.6.1/package.json#L40
