Grunt unable to locate JSDoc (wrong installation/environment)

Recently I set up Himins (a server-side node project) to properly build using Grunt. I got every tool working awesomely in my gruntfile.js except for JSDoc! Grunt give me this clue:

I had previously installed JSDoc with NPM globally and tested it on the command line. Googling around didn’t turn up much at first. I was not going to move JSDoc to a non-standard location just for Grunt!

This blog post, The Best Document Generator for Node, gave me the clues I needed to resolve the problem!

I just had to add

to my gruntfile.js!

Why Grunt doesn’t look for JSDoc there in the first place is weird to be. All it’s friends are there. The sample code for using the JSDoc Grunt plug-in doesn’t mention this issue.

You can find my full guntfile.js here.
