therubyracer install error
rubygems, therubyracer
Solution
You can use the Libv8 from the brew instead of the one from gem. You can do that by following commands:
$ gem uninstall libv8
$ brew install v8
$ gem install therubyracer
Problem
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 libv8 Building native extensions.
