Cannot find module 'karma' while using grunt

Question

I am using Yeoman toolkit to bootstrap an Angular web application. I've followed all the steps mentioned here. But still, apparently, grunt can not find the karma module. It spits out this error:

Loading "grunt-karma.js" tasks...ERROR >> Error: Cannot find module 'karma' Warning: Task "karma" not found. Use --force to continue.  Aborted due to warnings. 

I've tried installing karma both locally and globally using npm, but nothing seems to work.

Answer 1

Make sure you have installed both karma and grunt-karma before running the grunt task:

npm install karma npm install grunt-karma 

EDIT: One liner:

npm install karma grunt-karma 

Answer 2

I had to install the following

  npm install phantomjs   npm install jasmine-core   npm install karma   npm install grunt-karma 

Goodluck, Rajesh

Edit: One liner:

npm install karma grunt-karma jasmine-core phantomjs
