Here's my Gruntfile.js http://pastebin.com/JZU5bbDk
and my package.json http://pastebin.com/umYsnWi1
I did npm install
inside the main directory of my workspace (using WAMP) and it installed node_modules
folder with a bunch of subfolders inside.
I went to the nodejs command prompt and went to the directory so c:\wamp\www\thework
and typed grunt watch
and I get
Running "watch" task
waiting....
and when I tried to change anything in any file in that folder ... I got nothing. It didn't notice.
