I have the same problem, apparently it comes from the dependency "canvas", the branch comes from a PR. This PR is from 2013, so I am guessing there is an old dependency.

This should be fixed with the new version of the module. It uses the latest spritesmith which relies on node's built in pixelsmith by default.
