ruby-on-rails - Rails 安装失败并出现名称错误

问题描述

运行后sudo gem install rails或gem install rails在我的 ubuntu 系统上失败并显示以下消息。我是红宝石新手，无法弄清楚。

$ sudo gem install rails
/usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:50:in `<class:Specification>': undefined method `rubyforge_project=' for class `Gem::Specification' (NameError)
    from /usr/lib/ruby/vendor_ruby/rubygems/defaults/operating_system.rb:49:in `<top (required)>'
    from /snap/ruby/201/lib/ruby/3.0.0/rubygems.rb:1348:in `require'
    from /snap/ruby/201/lib/ruby/3.0.0/rubygems.rb:1348:in `<top (required)>'
    from <internal:gem_prelude>:2:in `require'
    from <internal:gem_prelude>:2:in `<internal:gem_prelude>'
