【问题讨论】：

在ajax-datatables-rails gem 中查看对此issue 的评论

当我评论 ajax-datatables-rails gem 时会产生名称错误

【参考方案1】：

在 gemfile 中为 AjaxDataTablesRails 提供一些特定版本，例如 (gem 'ajax-datatables-rails', '~> 1.0.0' ) 而不是像这样给出 (gem 'ajax-datatables-rails') 。 保存此更改后，让我们在终端上执行此命令（bundle install）。 现在你执行 rake db:create command 。 并执行以下命令 rake db:migrate 然后启动您的服务器 rails s
