Docpad@6.69 error installing "node./cyclic.js"

This is the result I see when I try to install docpad.

Error ambi@2.2.0 preinstall: node ./cyclic.js

spawn ENOENT

The ambi@2.2.0 preinstall script failed. This is most likely a problem with the ambi package, not with the new itself.

Is this a docpad installer bug or an npm bug?
