RVM problems installing ruby 2

Question

I did rvm get stable

Then I tried to install ruby 2.0.0

$ **rvm install 2.0.0** 
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-2.0.0-p0.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for smf, might require sudo password.
Installing SM Framework.
Error running 'requirements_smf_install_sm',
please read /usr/local/rvm/log/ruby-2.0.0-p0/smf_install.log

$ **cat /usr/local/rvm/log/ruby-2.0.0-p0/smf_install.log**
[2013-03-28 20:58:11] requirements_smf_install_sm
SMF Framework support is only intended for RailsInstaller, please use Homebrew integration instead.

The error log is not very helpful. I am on Mac OS X Mountain Lion. Any help?

Answer 1

It's because RVM was set to use a different library system: SMF. You need to set RVM to use brew instead. Here is page on rvm autolibs https://rvm.io/rvm/autolibs/

Use rvm autolibs show to see what your current setting is and if you are using brew, you can change it with rvm autolibs brew

Answer 2

Try running

brew update

If you don't have brew installed there is a good guide here to doing the whole installation process, you can ignore the 1.9.3 stuff and replace it with 2.0.0
