我在我的gemfile中添加了omniauth gem并试图运行bundle install，但是收到了有关rails和bundler版本不兼容的消息 . 我试图更新rails，但收到有关与其他gem不兼容的消息 . 如何将bundler降级到1.0？

$ bundle install
Fetching gem metadata from http://rubygems.org/......
Fetching gem metadata from http://rubygems.org/..
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`?

和

$ bundle update rails

  In Gemfile:
    factory_girl_rails (>= 0) ruby depends on
      bundler (~> 1.0.0) ruby

  Current Bundler version:
    bundler (1.1.1)
ruby-on-rails-3 gem bundler omniauth gem-bundler

    请尝试以下命令：

    gem uninstall bundler
gem install bundler --version '1.0.0'

    要安装降级版本的bundler，请尝试：

    gem install bundler --version '<= 0.10.6'

    所以你可以安装两个版本（检查： gem list bundler / bundler _0.9.26_ -v ），然后使用该特定版本运行，例如：

    bundle _0.9.26_ install
