NPM installations go bad

I have been trying to get Titanium Studio to work for a while. I am using Linux Mint XFCE Edition.

I need to install nodejs and packages titanium, alloy, acs, acs-node with npm.

Now every time I install nodejs again and install titanium or alloy through npm, it creates a new directory /[sudo] password for username: /home/ioan/[sudo] password for username: /usr/lib/node_modules I actually have a directory called [sudo] password for username:in my root directory (where username is my username).

All other packs that I need to install (acs, acs-node) give me:

> ws@0.4.31 install /[sudo] password for username: /home/ioan/[sudo] password for username: /usr/lib/node_modules/acs/node_modules/socket.io/node_modules/socket.io-client/node_modules/ws
> (node-gyp rebuild 2> builderror.log) || (exit 0)

I really hope someone can help me! I don’t understand what is going on. I am installing nodejs from PPA: https://launchpad.net/~chris-lea/+archive/node.js/ because the version from the Linux Mint repository is old.

Any help is much appreciated!
