Answer 1

When I tried the accepted answer, libv8 would install successfully with gem install libv8, but bundle install would fail on libv8. I think that bundle install was trying to install a different version of libv8. I was able to find a solution that worked for me.

I needed libv8 because therubyracer depends on it. To get it to install, I noted the version that was failing to install in the gem_make.out log for therubyracer. (The path for the gem_make.out log will be in the failure message.) In my case it was 3.16.14.7. (This version will probably change over time, in case you're reading this three years from now.) Then I did this:

gem install libv8 -v 3.16.14.7 -- --with-v8-lib <-- note different flag from accepted answer

which allowed this to work:

gem install therubyracer

which allowed me to complete my bundle install.

This worked for me on OSX Yosemite.
