Okay here's probably an easy one for anyone familiar with Ubuntu.
I have installed NodeJS (v.0.10.10) and NPM. I ran:
sudo npm install -g grunt-cli
sudo npm install -g grunt
(in every combination)
but although everything seems to install successfully, i.e. I see in /usr/lib/node_modules the grunt-cli folder and I navigate to the bin, and see the grunt exe, when I try to type grunt, I don't get any errors, but just nothing except the next command line prompt.
BTW - I've tried installing jasmine-node globally as well with the same results.
I installed npm and nodejs from Chris Lea's PPA.
