Ruby gem错误(Ruby on Rails)

Question

我的gemfile仍然有一个错误，我可以下载所有的gem，但是在'rails server‘的时刻，我得到了这个错误：

/home/administrador/.rvm/gems/ruby-2.4.0/gems/bundler-1.13.7/lib/bundler/runtime.rb:94:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'will_paginate'. (Bundler::GemRequireError)

这是我的gemfile：

source 'http://rubygems.org'

gem 'rails', '3.0.5'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2', '~> 0.2.6'
gem 'prawn', '0.8.4'
gem 'jquery-rails'
gem 'carrierwave'
gem 'will_paginate', '2.3.15'
gem 'net-ldap', '0.3.1'
gem 'cancan', '1.6.10'
gem 'therubyracer'

如果你能帮我解决这个问题，我将不胜感激！非常感谢

编辑:我已经尝试在我的gem文件中添加"gem 'will_paginate'，'~> 3.1.0'“。当我运行rails服务器时，我得到了这个错误

/home/administrador/.rvm/gems/ruby-2.4.0/gems/bundler-1.13.7/lib/bundler/runtime.rb:94:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'cancan'. (Bundler::GemRequireError)

只需使用以下命令更新您的gemfile

gem 'will_paginate', '~> 3.1.0'

rails 3或3+版本需要更高版本才能进行分页
