我尝试在 rails 应用程序上部署 ruby​​。我收到了这个错误

/usr/local/rvm/gems/ruby-1.9.3-p125@global/gems/bundler-1.2.0/lib/bundler/runtime.rb:31:in `block in setup': You have already activated rack 1.5.1, but your Gemfile requires rack 1.4.4. Using bundle exec may solve this. (Gem::LoadError)

我添加到 Gemfile

 gem 'rack' '1.5.1'

跑了

bundle update rack

我收到以下错误

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    rails (= 3.2.8) ruby depends on
      rack (~> 1.4.0) ruby

    rack (1.5.1)

我跑了

 bundle exec

返回

bundler: exec needs a command to run
