Whenever I try to use this plugin, I always get the above error.
All I am saying is:
build: ['temp/', 'public/']
I did npm install grunt-contrib-clean and I also loaded it in grunt. Those folders exist.
npm install grunt-contrib-clean
Jeez, I'm really sorry we didn't respond to this Chris! We messed up the @latest tag on npm for this repo and you were probably installing the version that was configured for grunt 0.4 (which we are releasing on Monday). Did you get this sorted?
I ended up moving up to Grunt 0.4 as it seemed like the community wasn't really focused on supporting 0.3 anymore. With that said, this module works great on 0.4!
