如何修复Rails 3（bundler）中的这个gem依赖问题？
由于某种原因，每次我尝试运行bundle install时，我的项目都搞砸了，现在它的抛出错误。 通过重新排序我的Gemfile的gem，我设法解决了一些错误，但现在我得到了这个：
Bundler could not find compatible versions for gem "faraday": In Gemfile: omniauth depends on faraday (~> 0.7.3) twitter depends on faraday (0.6.1)
我认为使用bundler应该删除依赖wtf's ？ 我假设这个消息意味着两个gem需要2个不同版本的faraday ..？
我怎么能解决这个问题呢？ 为什么不安装这两个版本，每个gem加载它想要的版本？
我喜欢这方面的帮助！
谢谢

您正在使用的Omniauth的特定版本取决于法拉第〜> 0.7.3，而Twittergem的最新发布版本需要0.6。
您可以通过使用存储库中的最新版本的Twitter gem来解决此问题。
gem 'twitter', :git => 'https://github.com/jnunemaker/twitter.git'
我有完全相同的问题，它通过我的Gemfile中的以下两行解决：
gem 'twitter', :git => 'https://github.com/jnunemaker/twitter.git' gem 'omniauth', :git => "git://github.com/intridea/omniauth.git" ,:ref => "b9fe79961ab56041dbf9"
尝试删除您的Gemfile.lock（文件），然后执行
bundle install
