ruby-on-rails - Gem 依赖冲突

Question

我遇到了与一年多前发布的上一个问题类似的问题。 How do I fix this gem dependency problem in Rails 3 (bundler)?

我是 ROR 的新手。尝试在应用程序上运行 bundle install 时，我收到以下信息:

无法在任何来源中找到 twitter-2.5.0

我试图删除我的 Gemfile.lock。并再次尝试 bundle install。并收到输出:

Bundler could not find compatible versions for gem "faraday":
  In Gemfile:
    twitter (>= 0) ruby depends on
      faraday (~> 0.8) ruby

    omniauth (~> 0.3.2) ruby depends on
      faraday (0.7.3)

来自 gem list 的结果

我还尝试了将 gem 'twitter', :git => 'https://github.com/sferik/twitter.git' 添加到我的 gemfile 的建议，但也没有成功。

如有任何帮助，我们将不胜感激。谢谢。

这个答案已经很晚了，但是你无意中升级了 twitter gem，它在此处的评论中被作为 gruzy notes 猛拉。

只需指定另一个 repo，其标签不会为您损坏且不会与 faraday 冲突。对我来说，这是:

gem 'twitter', :git => 'https://github.com/sferik/twitter.git', :tag => 'v2.2.0'

您可能只是将 v2.2.0 替换为 v2.5.0，破损应该消失了。
