もし以下のような警告なでるのであればruby gemをupgradeしよう

 Warning: You're using Rubygems 1.8.24 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.
 * bin/rake: generated with spring
 * bin/rails: spring inserted

libv8だけ入れる場合

gem install libv8 -- --with-system-v8

bundle でインストールする場合には

gem uninstall libv8
brew install v8
gem install libv8 -- --with-system-v8

gem uninstall libv8
brew install v8
bundle config build.livb8 --with-system-v8
bundle install

上のでもだめだったら以下のものでしてみる

therubyracerを入れる場合

http://stackoverflow.com/questions/19577759/installing-libv8-gem-on-mavericks

Because libv8 is the interface for the V8 engine used by therubyracer, you may need to use libv8, even if you have V8 installed already. If you wish to use your own V8 installation, rather than have it built for you, use the --with-system-v8 option.

gem uninstall libv8
gem uninstall therubyracer

Setup Spring

rspecをすでに使っていることが前提

http://girders.org/blog/2014/02/06/setup-rails-41-spring-rspec-and-guard/

spring binstub --all
* bin/rake: spring already present
* bin/rspec: generated with spring
* bin/rails: spring already present

私の場合はこれだけだったので

* bin/rake: generated with spring
* bin/rails: spring inserted

gem 'spring-commands-rspec'を追加する

その後もう一度spring binstub --all

* bin/rake: spring already present
* bin/rspec: generated with spring
* bin/rails: spring already present

これでrspecでspringを使えうようになる

start stop status

> spring status

Spring is running:

 7335 spring server | yourapp | started 4 hours ago
88294 spring app    | yourapp | started 2 hours ago | development mode

> spring stop

Spring stopped.

guard設定

guard :rspec do
# to
guard :rspec, cmd:"spring rspec" do
