I have searched for this problem and couldn't find relevant similar questions. Please bear with me if this is repetitive.
I have followed guides in RVM website to install RVM and I have installed rubies:
syed@rails:~$ rvm list
rvm rubies
ruby-1.8.7-p302 [ i386 ]
=> ruby-1.9.2-p0 [ i386 ]
As you can see I have made ruby-1.9.2 my default.
This is my gem directory:
syed@rails:~$ rvm gemdir
/home/syed/.rvm/gems/ruby-1.9.2-p0
Now, I tried to install rails and I am thrown the following error:
syed@rails:~$ gem install rails
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /home/syed/.gem/specs
I even did this without making any difference to the error:
syed@rails:~$ chown -R syed /home/syed/.rvm/
Currently, my environment looks like this:
syed@rails:~$ gem environment

I don't understand why it is trying to install gems to my system gem directory path?

RVM stands for Ruby Version Manager. It is a command line tool which allows you to easily install, manage and work with different Ruby environments. With RVM, you can easily install different versions of Ruby and easily switch between them.
RVM supports most UNIX like systems and Windows (with Cygwin or Bash on Ubuntu on Windows). The basic requirements are bash , curl , gpg2 and overall GNU version of tools - but RVM tries to autodetect it and install anything that is needed.
As you can see, RVM is a versatile tool that can be used to manage projects and entire Ruby environments. You can use RVM to configure development conditions, server installations, and even to deploy your application.
I had this same problem and I resolved it by doing the following:
sudo mkdir ~/.gem/specs
sudo chmod 777 ~/.gem/specs
It seems that RVM was trying to create this "specs" folder, but didn't have permissions to do so.
