I think you have a permission problem there. It's best if you use su (or sudo su) to become root, and then run the commands in the root shell from there, using sudo like you're doing might not work correctly.

Edit:

To install without root privileges do not use sudo:

> cd $HOME
> bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
