当我尝试运行时rails generate scaffold test，总是显示以下错误

C:\Lab\railapps\dbtest>rails generate scaffold test
      invoke  active_record
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `require': Please install the oracle_enhanced_adapter: `gem install activerecord-oracle_enhanced-adapter` (cannot load such file -- active_record/connection_adapters/oracle_enhanced_adapter) (LoadError)
    from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `block in require'"

我当时确实安装了oci8gem activerecord-oracle-enhanced-adapter。你能帮我看看吗？非常感谢。

版本信息

我的猜测是activerecord-oracle_enhanced-adapter并且oci8不在您的 Gemfile 中。Ruby on Rails 现在默认使用Bundler来管理依赖项。

尝试添加以下行：

   gem "activerecord-oracle_enhanced-adapter"
   gem "oci8"

到您的 Gemfile（位于项目目录的根目录）并运行bundle install. 然后尝试构建你的脚手架。
