应用错误收集

我无法在Ruby on Rails 4.1.4中安装activerecord。

我已将gem 'activeadmin', github: 'activeadmin'添加到Gemfile的末尾并运行bundle install。它返回0，所以我试图运行rails g active_admin:install命令，但它返回以下错误：

NameError：未定义的局部变量或方法install' for main:Object from (irb):3 from E:/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.1.4/lib/rails/commands/console.rb:90:in从'开始' E：/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.1.4/lib/rails/commands/console.rb：9：来自start' from E:/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.1.4/lib/rails/commands/commands_tasks.rb:69:in控制台' E：/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.1.4/lib/rails/commands/commands_tasks.rb：40：在来自run_command!' from E:/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.1.4/lib/rails/commands.rb:17:in' E：/ work / projects / src / technical_support_timer / bin / rails：4：require' from E:/work/projects/src/technical_support_timer/bin/rails:4:in'来自-e：1：in load' from -e:1:in'

为什么呢？我究竟做错了什么？我该如何解决？

提前致谢。
