找不到 gem 安装了捆绑器

Question

对于我的 PHP Symfony 应用程序，我需要 Compass 和 Sass。两者都应该安装在我的项目的 vendor/bundle 文件夹中。

这是我目前所做的：

$ gem install bundler
Successfully installed bundler-1.10.6
1 gem installed

$ bundle install --path vendor/bundle
Fetching gem metadata from https://rubygems.org/...........
Fetching version metadata from https://rubygems.org/...
Fetching dependency metadata from https://rubygems.org/..
// ... Installing some gems
Using bundler 1.10.6
Bundle complete! 2 Gemfile dependencies, 10 gems now installed.
Bundled gems are installed into ./vendor/bundle.

好了，现在轮到我的问题了。当我执行已安装的 gems 之一时，出现以下错误：

$ vendor/bundle/ruby/1.9.1/bin/compass 
/usr/local/rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:315:in `to_specs': Could not find 'compass' (>= 0) among 30 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/usr/local/rvm/gems/ruby-1.9.3-p551:/usr/local/rvm/gems/ruby-1.9.3-p551@global', execute `gem env` for more information
    from /usr/local/rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:324:in `to_spec'
    from /usr/local/rvm/rubies/ruby-1.9.3-p551/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_gem.rb:64:in `gem'
    from vendor/bundle/ruby/1.9.1/bin/compass:22:in `<main>'

我知道它在 $GEM_PATH 中查找，但当然找不到。但是我该如何解决这个问题呢？我不想更改项目文件夹的 gem 路径。

与Bundle you should launch the application with the Bundle Exec command。对于发射罗盘，你可以这样做，例如：

$ bundle exec compass watch

或

$ bundle exec compass compile
