I don\'t manage to install therubyracer gem on Yosemite 10.10.
Here is the log:
11:53 $ gem install libv8 -v \'3.16.14.3\' -- --with-system-v8 Building
I was able to proceed with ruby racer after rm Gemfile.lock
rm Gemfile.lock
beforehand: I installed v8 via brew install v8, and then did gem install libv8 -v '3.16.14.3' -- --with-system-v8
brew install v8
gem install libv8 -v '3.16.14.3' -- --with-system-v8
and I am running 10.10 Yosemite
