Ruby on rails 使用activerecord sqlserver适配器时出错

我安装了activerecord sqlserver适配器，以便它出现在我的本地gems中。 正在运行命令

rails generate scaffold Tablename fieldname:fieldtype

返回一个错误（如下所示）。我已经安装了rails 1.9.2。如蒙指导或协助，将不胜感激。谢谢

您的

gem文件中是否列出了gem

添加到您的文件（）

然后再次运行
捆绑安装
最终解决了这个问题。为了修复这个问题，我卸载了两个冲突版本的activerecord sqlserver适配器，安装了ruby odbc gem，安装了activerecord sqlserver适配器，调整了gem文件以反映正确的版本，然后运行了bundle更新，然后bundle安装，最后rails生成了scaffold。。。命令。
您是否尝试过
bundle exec rails generate scaffold tablename fieldname:fieldtype
？我现在尝试过了。同样的错误。一定与gem的版本/位置有关，但我看不出这有什么错-（我在站点gemfile中添加了上面的代码，并运行了bundle安装。虽然有了一些改进，但主要错误仍然存在——rails似乎找不到ActiveRecodSQLServer适配器
