我在Snow Leopard盒子上运行带有SQLite3的Rails 2.3.4，没有任何问题。我刚刚完成了一个需要2.3.5的新项目，因此我进行了sudo gem更新以获取最新版本的Rails。这安装得很好，但是当我运行rake db：migrate时，出现以下错误：
rake aborted!
uninitialized constant SQLite3::Driver::Native::Driver::API
我尝试重新安装sqlite3 gem（通过：sudo gem install sqlite3-ruby），但仍然遇到相同的错误...
我有XCode 3.2（并且在2.3.5更新之前一切正常）
任何帮助将不胜感激，因为我不知道如何解决此问题！

编辑：这是我在sqlite3-ruby上运行安装时的输出：

最佳答案
我知道了！我是从Leopard下的源代码构建了Ruby副本的，并且自升级以来没有重建它。不能完全确定为什么它可以与2.3.4一起使用，但不能与2.3.5一起使用-必须有所更改。
我只是从定制版本更改为Snow Leopard随附的副本，重新运行了gem更新，一切都变好了！
