Every time I run rvm install ruby-1.9.2-p320
I get the following message.
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-1.9.2-p320.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
Can not find compiler and 'make' tool - make sure Xcode and/or Command Line Tools are installed.
Requirements installation failed with status: 11.
I am just starting to try to learn to program and I understand I need to be able to install and run different versions of ruby other than the default 1.8.something. I have close to no idea what I am doing so please dumb-down any answer. Thanks in advance.
