如何在10.10优胜美地上安装therubyracer宝石？
我无法在优胜美地10.10上安装therubyracer gem。
这里是日志：

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

Gem files will remain installed in /usr/local/var/rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/therubyracer-0.12.1 for inspection.
Results logged to /usr/local/var/rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-14/2.1.0-static/therubyracer-0.12.1/gem_make.out
git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #note that libv8 version may change, so tab through files in pkg/, also remember to use the one with version specified
然后把你的项目宝石捆绑在一起
这是它在10.10上为我工作的唯一方式（ruby 2.1.2）
gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8
这是它在10.10上为我工作的唯一方式（ruby 2.1.2）
或者试试gem install libv8 -v 'XX.XX.XX' -- --with-system-v8添加gem的版本:)
这次没有任何答案适用于我。 我也使用这个：
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
看到rubyracer Github的问题。
希望它可以帮助别人。
