Error installing any ruby version with RVM on OSX

Question

Guys I'm about to kill myself with this one!

I had some problems with RVM installing multiple versions of Ruby, and following a thread on Stackoverflow I decided to remove it completely. After reinstalling RVM, I am unable to install any Ruby version at all.

• Mac OS X
• RVM 1.20.10 stable
• Homebrew 0.9.4

Here are some logs:

rvm install 2.0.0-p0

or:

rvm install 2.0.0-p195 --autolibs=enabled

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.

Help!

Answer 1

I ran into the same issue, you need to manually install all the required packages using Brew. For me I had to run the following installs:

brew install autoconf
brew install automake
brew install libtool
brew install apple-gcc42
brew install libyaml
brew install libxslt
brew install libksba
brew install openssl

You just need to keep running "rvm requirements" and reading the log and installing the packages needed until there are no more errors.

Answer 2

After installing RVM, You'll want to run

rvm requirements

to see if anything else is required to install ruby and rails first.
