I am using node version 0.12.2 and npm version 3.3.6. I am using yeoman tool to create angular app. When i run grunt it is aborting at imagemin dependency. I tried command npm install -g grunt-contrib-imagemin and npm install imagemin too.Still i am facing the same error:

  • See if updating to latest version of Node (version 4.2.X) makes a difference. Also if you are using a Windows machine, while doing ``npm install`` , did you get an error like ``pre-build test failed`` ? – Prayag Verma Jan 03 '16 at 11:05

Clean your npm cash and reinstall grunt-contrib-imagemin

npm cache clean && npm install grunt-contrib-imagemin
