No npm global module required

Question

I have the following problem. I install uuid with npm install -g uuid. When I try to run the following code:

var uuid = require("uuid");
console.log(uuid.v1());

an exception is thrown:

module.js:339
throw err;
^

Error: Cannot find module 'uuid'
at Function.Module._resolveFilename (module.js:337:15)
at Function.Module._load (module.js:287:25)

at Function.Module.runMain (module.js:467:10)

If I install the module locally with npm install uuid, it works fine. But why? What should I do to make my global packages work? I tried to download it from Language & Frameworks -> Javascript -> Libraries, but I still get an exception if I do not install it locally for my project.

Thanks in advance.
