node.js - Grunt fail build "Arguments to path.join must be strings" error -


updated node 0.10.0, while grunt server still works, grunt (build) , grunt test return "arguments path.join must strings" error on running "useminprepare:html" (useminprepare) task, failing build.

set up: node: 0.10.0 yeoman: 1.0.0-beta.3 grunt: grunt-cli v0.1.6, grunt v0.4.0rc7

i know there's fix been made, tried suggested solutions (npm cache clear, grunt reinstall, etc.) no success.

any appreciated.

this question has been answered before here: yeoman yo webapp fails typeerror

to quote myself:

this error in bower , got fixed. can manually update bower installation or wait updated generators. this commit fixed issue.
