node.js - Global node modules not recognized -

i reading around , still can't fix it. installed grunt-cli , bower global , when run get

bash: grunt: command not found 

so didn't have .bash_profile , added it. , put inside:

export path=/.node/lib/node_modules:$path 

but still not working. if need prefix is:

prefix = "/root/.node" 

i using debian.

did remember reload bash profile after creating it? if not, open terminal , type source ~/.bash_profile

this exit shell , log in can recognize changes made it.
