therubyracer - Gem::Ext::BuildError: ERROR: Failed to build gem native extension

Question

I\'m trying to install the following gem versions on Mavericks

• libv8 (3.16.14.3)
• therubyracer (0.12.1)

Obviously therubyracer gems depe

Answer 1

This has worked for me:

gem install libv8 -v '3.16.14.17' -- --with-system-v8
brew install v8-315
gem install therubyracer -v '0.12.3' --source 'http://rubygems.org/' -- --with-v8-dir='/usr/local/opt/v8@3.15'

For the last command check the output of brew --prefix v8-315 in my case it was /usr/local/opt/v8@3.15.
