I am running a VM with Ubuntu Server 12.04. 
I try to install a Ruby on Rails Application and first of all i needed to install Curl (which is done) and now i try to install RVM.

I am following this installation guide : [ruby on rails installation](https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm)

i am at the step when i have to run rvm to check. But it won't load when i try to enter :

```
source ~/.rvm/scripts/rvm

```

UPDATE :

I have this folder /usr/local/rvm

when i try to run this : `rvm requirements`

he says : the program 'rvm' is currently not installed....

but i did with this command :

```
\curl -L https://get.rvm.io | bash -s stable

```

as shown in the tutorial, or didn't it install ? i have no errors...
i even see : thank you for using rvm!

-sh: 1: source: not found

any ideas? i am relatively new to ubuntu. thanks in advance
