therubyracer - Gem::Ext::BuildError: ERROR: Failed to build gem native extension
This steps worked for me.
OS: MaverickRuby: 2.1.1
gem uninstall libv8gem install therubyracer -v '0.11.3'gem install libv8 -v '3.11.8.13' -- --with-system-v8
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/versionsbrew install v8-315gem install libv8 -v '3.16.14.13' -- --with-system-v8gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315bundle installI had also run brew install gcc prior, but I'm not sure whether this was in fact necessary.
Try first uninstalling libv8 gem, then install rubyracer, and then libv8
gem uninstall libv8gem install therubyracergem install libv8 -- --with-system-v8
