Better error message if PM2 is misconfigured / throwing EACCES error messages

[kevinburke]

If you configure/install PM2 as a root user, and then attempt to run any commands (help, version) as a non-root user, you get a cryptic error message:

$ pm2 --version
events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: connect EACCES /home/ubuntu/.pm2/rpc.sock
    at Object.exports._errnoException (util.js:870:11)
    at exports._exceptionWithHostPort (util.js:893:20)
    at PipeConnectWrap.afterConnect [as oncomplete] (net.js:1063:14)

This is confusing. It would be better if pm2 could catch the error and report something like "Permission denied, double check you have not installed pm2 as root" or something.

good idea

Fixed on recently published pm2 (2.7.0):

$ npm install pm2@latest -g
$ pm2 update

Let me know if there is any issue
