therubyracer install error

Question

As you can see below, libv8 installs fine, but therubyracer doesn\'t. I\'m using Mac 10.7.4.

~/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1> gem install lib         


        

Answer 1

On Mountain Lion 10.8, it doesn't come preinstalled with a C compiler. You'll need to download and install the 'command line tools' package from Apple themselves, and then run which gcc to confirm it is installed. Everything should run fine from there on in.
