Trouble installing Ruby 2.0.0-p247 via RVM (OSX Mountain Lion)

Question

My ultimate goal is to install the current version of Ruby on Rails. I am running on OS X Mountain Lion. Here's my process so far:

Installed RVM

$ \curl -L https://get.rvm.io | bash -s stable

Checked for known (and I assume approved) installs

$ rvm list known

I see that the current stable build is available

[ruby-]2.0.0[-p247]

Key in command to install

$ rvm install 2.0.0-p247

Note: I also tried these install commands

$ rvm install ruby-2.0.0-p247
$ rvm install ruby=2.0.0-p247

I'm getting nowhere fast. Results:

$ rvm install 2.0.0-p247
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-2.0.0-p247.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Installing requirements for osx, might require sudo password.
Certificates in '/usr/local/etc/openssl/cert.pem' already are up to date.
Requirements installation successful.

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

I also ran this command in debug mode. To avoid clutter, you can access it here.

Also, here is the log:

This is my first installation via RVM. $rvm list returns no gems.

Please ask if any additional information might be helpful.

Edit - HERE is the log in case that might help anyone.

Answer 1

Something must have been wrong with either my Xcode or my Command Line Tools install. Reinstalling both made everything run beautifully.

Answer 2

For those that arrived here from google when you applied the same error as the query:

I got this same problem but did not want to go through the ridiculously long process of reinstalling xcode like the accepted answer suggested. All I did was run
rvm get stable And then run
rvm install ruby-2.0.0-p247 again

my original problem



then after I ran
rvm get stable
