Devise-RoR：错误运行rails生成devise：install

Question

Can someone help me??

I'm following the "Getting Started" instruction from https://github.com/plataformatec/devise and when I run rails generate devise:install I got the following error (My ruby is version 1.8.3 and Rails 3.2.17):

Answer 1

The version of devise you are trying to use( Devise 3) isn't compatible with Ruby 1.8.3

If it is possible update your Ruby to 1.9.3 or newer.
