Gemset '' does not exist, 'rvm ruby-1.9.3-p547 do rvm gemset create ' first, or append '--create'.

I get one error while try to install ruby 1.9.3 with rvm 1.25.28

rvm install 1.9.3

Error: 
There was an error while trying to resolve rubygems version for 'latest'.
Halting the installation

rvm use 1.9.3

Error:
Gemset '' does not exist, 'rvm ruby-1.9.3-p547 do rvm gemset create ' first, or append '--create'.


To solve the above error
rvm use 1.9.3@newgemset --create --default

Hope this helps who install ruby 1.9.3 with rvm 1.25.28

{ [Error: getaddrinfo ENOENT] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' }

You may get this error when you send request to any URL from nodejs,
Simply you can solve this error by doing following

1. Find out IP of url (which you try to access from your code)
2. Add that url and domain in your /etc/hosts as below
     111.111.111.111    example.com


Cheers !!

Upgrade NodeJS

Install node module 'n', this module helps nodejs version managements
Do as below

1. $npm install n -g
2. n 0.8.8
