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

For those facing this problem in OS X El Capitan, this solution from a therubyracer issue thread was what finally worked for me:

brew tap homebrew/versions
brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install

I had also run brew install gcc prior, but I'm not sure whether this was in fact necessary.
