How does one install grunt on Ubuntu 13.04?

I've attempted to install it via NPM:

sudo npm install -g grunt

Then when i run grunt:


But it doesn't seem to work it throws an error:

        throw new TypeError('Arguments to path.resolve must be strings');
              ^ TypeError: Arguments to path.resolve must be strings
    at Object.exports.resolve (path.js:313:15)
    at Object.<anonymous> (/usr/local/lib/node_modules/grunt/bin/grunt:13:16)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3

Here's some information about what version of node i have:

$ npm -v

Did you really mean to run the command sudo npm install -g grunt $ grunt? Shouldn't sudo npm install -g grunt be sufficient? I think the $ isn't valid syntax for the npm install command. – gertvdijk Aug 27 '13 at 16:28
I'm illustrating the prompt. Sorry no $ needed. Also, was that the reason why you downvoted? Sorry i can change that if you'd like. – chrisjlee Aug 27 '13 at 19:36

You should avoid using sudo with npm! – nicholaschris Aug 15 '14 at 10:19

I believe you want: npm install -g grunt-cli which installs the command line tool. You install grunt (and modules) locally in each project

Docs here to back up my words;

I just installed grunt from PPA. Here is a full list of steps that I had to take to get a working grunt build:

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update 
sudo apt-get install nodejs
# remove a conflicting install of npm that I had tried earlier
sudo apt-get update && sudo apt-get -y dist-upgrade
sudo npm install -g grunt grunt-cli grunt-contrib-clean grunt-replace grunt-contrib-concat grunt-contrib-watch grunt-contrib-jasmine grunt-contrib-connect grunt-saucelabs grunt-gitinfo

Looks like the error occurs when there are two versions of grunt.

To find out if you have two versions of grunt installed you run in CLI:

where grunt or which grunt

If you see more than one version of grunt:


Then you just remove one of them:

rm /usr/local/bin/grunt

Wrote a post on this for more information.

I don't seem to have that where command available. – tutuca Aug 22 '14 at 1:32
@tutuca you can use which grunt instead – Kim Stacks Sep 10 '14 at 20:44
oh, I know... but where was interesting :P – tutuca Sep 11 '14 at 13:13
you can use this command whereis grunt instead of where – Piyush Dholariya May 21 '15 at 4:52
