我正在尝试安装最新版本的Globalize gem - 唯一与 Rails 5 兼容的版本。为此，我必须从 Github 安装它。因此，我按照自述文件的建议在 Gemfile 中添加了以下行：
gem 'globalize', git: 'https://github.com/globalize/globalize'
bundle install命令执行顺利。但是，globalize gem 没有显示在gem list（我认为从 Github 安装的所有 gem 也没有显示）但显示在bundle list.
当我运行bundle exec irb然后require 'globalize'工作正常。但它在rails console. 为什么？如何使宝石可用于导轨？
> rails c
2.4.0 :001 > require 'globalize'
LoadError: cannot load such file -- globalize
