ruby-on-rails - 我如何解决 Rails 3 (bundler) 中的 gem 依赖问题？

Question

由于某种原因，我的项目搞砸了，现在每次我尝试运行 bundle install 时都会抛出错误。我通过重新排序我的 Gemfile 中的 gem 设法修复了一些错误，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 应该消除依赖 wtf's？我假设此消息意味着两个 gem 需要 2 个不同版本的 faraday..？

我该如何解决这个问题呢？为什么它不只安装两个版本，每个 gem 加载它想要的版本？

我很想在这方面提供一些帮助!

谢谢

具体你使用的Omniauth版本取决于Faraday ~> 0.7.3，而最新发布的Twitter gem版本需要0.6。

您可以使用存储库中最新版本的 Twitter gem 来修复此问题。

gem 'twitter', :git => 'https://github.com/jnunemaker/twitter.git'
