我的 gemfile 仍然出现错误，我可以下载所有 gem，但是在“rails 服务器”的那一刻，我收到了这个错误：

/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'

如果您能帮我解决这个问题，我将不胜感激！非常感谢

编辑：我尝试将“gem 'will_paginate', '~> 3.1.0'” 添加到我的 gemfile.. 并且当我运行 rails server 时出现此错误

/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)
Gem Load Error is: uninitialized constant AbstractController::ViewPaths
Backtrace for gem load error is:

/home/administrador/.rvm/gems/ruby-2.4.0/gems/actionpack-3.0.5/lib/abstract_controller/rendering.rb:33:in `<module:AbstractController>'....(same as above)

【解决方案1】：

只需更新您的 gemfile

gem 'will_paginate', '~> 3.1.0'

rails 3 或 3+ 版本需要以上版本才能分页

参考这个https://github.com/mislav/will_paginate

对不起，但也不起作用...我收到以下错误：ruby-2.4.0/gems/bundler-1.13.7/lib/bundler/runtime.rb:94 :in `rescue in block (2 levels) in require': 尝试加载 gem 'cancan' 时出错。 (Bundler::GemRequireError) Gem 加载错误是：未初始化的常量 AbstractController::ViewPaths
你是否安装了 node.js 如果没有然后运行这个命令'sudo apt-get install nodejs'
是的，它安装在我的机器上。我不知道 ruby 版本（2.4.0）是否介于两者之间。
是的，有可能，尝试切换 ruby 2.3，希望它会工作
