Forum: Ruby Instalation problem

HI!!
I'm a complete newby and I'm trying to follow a tutorial on learning
ruby on rails.
I am on a new mac and require an updated version of ruby to follow
the tutorial. Everything I've read has pointed me towards downloading
and using RVM.
I typed \curl -L https://get.rvm.io | bash -s stable --ruby in my
terminal and this is a shortened version of what happened:


Upgrade of RVM in /Users/carlosamengual/.rvm/ is complete.

# Carlos Amengual,
#
#   Thank you for using RVM!
#   I sincerely hope that RVM helps to make your life easier and
#   more enjoyable!!!

There has been an error while running configure. Halting the
installation.

I see that rvm has been installed, but something has obviously gone
wrong...any ideas. This is like the third time I'm doing it because when
I try and install an updated version of Ruby I get similar messages.
Thanks in advanced for your help.

I am on Mac too. I installed rvm. I had the same error message you got. 
I am sorry for not having  a clear answer but even if I had this error 
message, ultimately everything worked perfectly: rvm, ruby 1.9.3 
installed.
I am not being arrogant but just want to make sure that you are not 
being alarmed for no reason. Are you sure the installation is not 
actually completed?
What do you see when typing this code in you Terminal?       which ruby
or you can type:    ruby -v

I don't use rvm but it sounds like you did not install Xcode which is
needed to compile ruby. You can get it from the app store

You might get more information using these commands: 'rvm notes' and 
'rvm
requirements'.

Since there's also compilation problems lately related to recent Xcode
versions, https://rvm.io/os/osx/ could be helpful

Hi,
My version is the same as prior to doing anything. ruby 1.8.7!!
This is driving me crazy!!
I also have Xcode installed, but have not done anything with...do I have 
to do something with it??
Thanks again!!

Yes! You have to install the command line tools. There are different 
version depending on what version of Mac OS X you are using, but you can 
either download the command line tools directly from Apple here:

https://developer.apple.com/downloads/index.action

or from within Xcode. You have to open he Preferences and in the 
Downloads tab there is a listing for Command Line Tools. Click the 
install button next to it and that will install all the parts needed.

Prefect!! Thanks for your help!!
I've now got Xcode up and running and GCC is also good!
Now I'm having problems with Homebrew...when I type brew doctor I get 
this message:


Warning: You have a non-Homebrew 'pkg-config' in your PATH:
  /opt/sm/pkg/active/bin/pkg-config

`./configure` may have problems finding brew-installed packages using
this other pkg-config.

The tutorial says it should say 'Your system is rearing to brew'
Any ideas?!?!
Thanks!!

You must have previously installed the SM framework <https://smf.sh/>.
It most likely put a line near the end of your .bashrc or .profile or
.bash_profile that adds its bin directories to your PATH; try
commenting that out. (I'm not sure what to advise if you actually need
to use SM; and this warning from Homebrew may not even be anything to
worry about.)

that??
