SQLite3和Ruby -未初始化的常量SQLite3 ...API接口
SQLite3和Ruby -未初始化的常量SQLite3 ...API接口
提问于 2009-12-02 18:46:02
我在windows下的NetBeans 6.7.1中使用Ruby on Rails，并且我正在尝试使用SQLite3。
我已经安装了windows版本的sqlite3-ruby，并将sqlite3.def、sqlite3.dll和sqlite3.exe放在了NetBeans6.7.1>ruby2>jruby-1.2.0>bin中
当我尝试运行db:create rake任务时，我得到如下所示的错误和跟踪。
有谁能帮帮忙吗？

您还可以通过安装jdbc等效项(jdbc-sqlite3 activerecord-jdbcsqlite3-adapter)将您正在使用的数据库适配器更改为jdbc-sqlite3数据库适配器，您应该可以从netbeans gem manager执行此操作

到目前为止，有不同的Ruby实现，其中之一是JRuby。
NetBeans捆绑了JRuby，它基于Java Virtual Machine并由Java Virtual Machine提供支持。
SQLite3/Ruby绑定与JVM不兼容，这需要原始的原生Ruby实现，也称为MRI (Matz Ruby实现或C Ruby)。
请安装一个单独的Ruby版本，然后将解释器添加到NetBeans菜单。
您可以找到有关将较新的1.8.6或1.9.1与Rails here配合使用的教程
我建议您从here安装1.8.6版的安装程序(候选版本1
希望这能有所帮助。
