Answer 1

This worked for me very well on my Yosemite and Ruby 2.1.5 (Ruby through RVM)

gem install libv8 -v '3.16.14.3' -- --with-system-v8

Earlier it was giving me error Gem::Ext::BuildError: ERROR: Failed to build gem native extension. for libv8 gem version 3.16.14.3

Answer 2

Only this works for me in my Yosemite, Ruby 2.1.2:

gem install libv8 -v '3.16.14.3' -- --with-system-v8
brew link --overwrite v8-315 --force
gem install therubyracer -v '0.12.2' -- --with-system-v8

Answer 3

Maybe it will be useful for someone but I had problems installing therubyracer (because of the problems with libv8) the solution was to uninstall all the libv8 that I had installed. Install therubyracer

$ gem uninstall libv8
$ gem install therubyracer -v '0.12.0'
Fetching: libv8-3.16.14.7-x86_64-darwin-14.gem ( 57%)
Fetching: libv8-3.16.14.7-x86_64-darwin-14.gem (100%)
Successfully installed libv8-3.16.14.7-x86_64-darwin-14
Building native extensions.  This could take a while...

I hope this helps someone.

After hours of trying simply upgrading ruby worked:

brew install ruby 

and then adding the following to gem file:

gem 'libv8'  
gem 'therubyracer' 

Answer 5

What worked for me, based on the following comment,

https://github.com/cowboyd/therubyracer/issues/304#issuecomment-62046085

was to remove Gemfile.lock and then run bundle install

A heads up to anyone that might have been having my issue: I ended up uninstalling my ruby version in RVM and then reinstalling it. That seemed to use the correct dependancies in the latest version of xcode tools for compiling ruby.

rvm list
rvm uninstall ruby-x.x.x
rvm install ruby-x.x.x
