Install package using npm

I am trying to install npm using :

sudo npm install azure@0.6.9
npm http GET https://registry.npmjs.org/azure/0.6.9
npm http 304 https://registry.npmjs.org/azure/0.6.9

npm ERR! Unsupported

npm not ok
$ node --version
v0.8.16

not sure where it is getting the version number from (or) why is the use in nvm also not taking into effect. Can you please let me know what I am missing
