Problems in installing Ruby and rails on Lion

Hi there,

I am a new Mac user + a new learner ruby on rails.
Now, I am trying to install rvm, ruby and rails on my Macbook Pro (I did it successfully on Window).

I can't even install rvm on my Mac (Lion OS). I used bellow command to install rvm

bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

after i finished this two line, I tested rvm by using command:

type rvm | head -1

it gave output "rvm is a function"

But after I restart my terminal, and retype this command "type rvm | head -1"
and i gave output: "rvm not found"

anyone know what is my problem, pls pls help me.

 

Thanks for your help.

all link provided are awesome.

Now I installed it successfully. and I already solved that problem.

After installed it, once ever we restart our terminal we have to use the command:

Source .bash_profile

to call it for using...

Cheers,
