我如何使用项目本地的Ruby Gem文件而不是系统上安装的gem？

Question

I have the SASS gem installed on my system (v3.3.8), but I have a project that requires v3.2.19). I also have a situation where there is a conflict on the system with v3.2.19 exsiting (Codekit won't compile SASS if any older versions of a gem are installed).

I used Bundler to install a copy of the required gems in a folder local to my project:

my_project/src/vendor/bundle/ruby/...

How can I force my project to use the ruby gems in the local folder for my grunt tasks, instead of those installed globally on my system?

# A sample Gemfile
source "https://rubygems.org"    

gem 'autoprefixer-rails', ">=1.2.0.20140609"
gem 'breakpoint', ">=2.0.7"
gem 'compass', ">=0.12.6"
gem 'sass', ">=3.2.19"
gem 'singularitygs', ">=1.1.2"

bundle exec是正确的命令。
