我在使用rvm时遇到了麻烦。首先我认为问题出在特定的宝石上。但现在我能够使用mysql2重现错误。我有麻烦来诊断这个问题......
这是最后一个日志。

为什么在这里搜索2.2.0？为什么不用2.2.3？ （顺便说一句，它没有安装在供应商下）

我认为类似的情况是this other question about pg。我遇到了麻烦，这就是我现在用mysql测试的原因。我甚至创建了一个bug at ruby, which was rejected，因为它是图书馆扩展的混合......
问题是什么是混合库。我的猜测是rvm。任何类似的情况？有任何诊断帮助吗？我可以使用pg和mysql2添加更多信息。
