我在Snow Leopard盒子上运行Rails 2.3.4和SQLite3没有任何问题。我刚刚完成了一个需要2.3.5的新项目，所以我做了一个sudo gem更新来获取最新版本的Rails。这安装正常，但当我运行rake db：migrate时出现以下错误：
rake aborted!
uninitialized constant SQLite3::Driver::Native::Driver::API
我已经尝试重新安装sqlite3 gem（通过：sudo gem install sqlite3-ruby），但我仍然遇到同样的错误......
我有XCode 3.2（在2.3.5更新之前一切正常）
任何帮助都会受到赞赏，因为我对如何解决这个问题感到茫然！

编辑：这是我在sqlite3-ruby上运行安装时的输出：

答案 0 :(得分：2)
我已经明白了！我在Leopard下从源代码构建了我的Ruby副本，并且自升级以来没有重建它。不完全确定为什么它适用于2.3.4但不适用于2.3.5 - 必须有所改变。
我刚刚将自定义构建的路径更改为Snow Leopard附带的副本，重新运行了宝石更新，一切都很好了！
