Can't install pm2 from deb about pm2

[Unitech]

Are you using a virtual machine/server ?
Tried to install it as root ?
Have you installed build-essential ?

server, ubuntu 12.04 lts, deb package installing with sudo

when i installing pm2,

sudo npm install -g

in my home dir appeared .node-gyp folder. Why? Also see the owners..

4 drwxr-xr-x 5 swix dialout 4096 Sep 3 19:13 0.8.21

Who is swix and dialout?

[Unitech]

There is no occurence of dialout or swix in PM2 code as you can see with grep :

⌬ tknew@Transport:~/Unitech$ grep -R "dialout\|swix" pm2/ | wc -l
0

This system issue is not linked with pm2, please use another place to solve this problem.
Thank you for your understanding.
Closing.
