Install random NPMs

Hi,

I received an error during implementing NPM's squel:

npm ERR! 404 no such package available : squel

npm ERR! 404

npm ERR! 404 'squel' is not in the npm registry.

npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

npm ERR! 404 It was specified as a dependency of 'js'

npm ERR! 404

npm ERR! 404 Note that you can also install from a

npm ERR! 404 tarball, folder, http url, or git url.

But this package is official released yet:https://www.npmjs.com/package/squel

Even when I try to install it locally on my machine, all seems to be fine:

How to install random NPMs with SPS12 ? I have no access to our linux Server - just to the WebIDE.

Thank you in advance!
