Can't run yeoman application with grunt, cdnify.js

I've project to join so I cloned repo from git. I have installed npm install and then bower install, but when I try to run the app with grunt serve command, console returns this:

Loading "cdnify.js" tasks...ERROR
>> Error: Cannot find module 'chalk'

Running "serve" task

Running "clean:server" (clean) task

Running "wiredep:app" (wiredep) task
Warning: ENOENT, no such file or directory '/home/tomek/dev/mobilas/app/bower.json' Use --force to continue.

Aborted due to warnings.

The thing is, I shouldn't really change neither Gruntfile.js nor bower.json file.

Link I referenced in comment above fixed it for me... just had to run

npm install chalk

in the project directory as a work around until they get one of the grunt dependencies fixed.
