ruby-on-rails-3 - 如何降级bundler或升级rails？

Question

我将omniauth gem 添加到我的gemfile 中并尝试运行bundle install，但收到一条有关rails 和bundler 版本不兼容的消息。我尝试更新 Rails，但收到有关与其他 gem 不兼容的消息。如何将 bundle 程序降级到 1.0？

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 3.0.0) ruby depends on
      bundler (~> 1.0.0) ruby

  Current Bundler version:
    bundler (1.1.1)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
