我刚刚从狮子升级到小牛队（似乎没有任何方式可以去山狮）。我有许多旧的铁轨项目，不同的红宝石和导轨版本。在狮子座上，我能够在红宝石1.8.7,1.9.2和1.9.2中正常工作，并在它们之间切换得很好。 1.8.7是系统ruby所以它不是真正的rvm，所以我做了rvm使用系统来使用它。
当我升级系统时，env变成了ruby 2，所以我尝试安装ruby 1.87并遇到了大量问题。
我最终爆炸了几次rvm以解决所有问题，但似乎仍然无法使我的1.8.7环境完全正常工作。我有几个需要本机编译的宝石。
我的最新一期是：in `require': no such file to load -- iconv (LoadError) 但是这些解决方案都不适合我。
我想知道我是否是唯一一个陷入这种情况的人，我找不到任何指南可以让这一切工作......有什么建议吗？
这是我当前的堆栈跟踪：

这听起来像是通过自制软件或macports编译软件包的非常旧的安装，其中大部分都可以正常工作，但很少有人可能只使用以前系统中可用的库，现在就可以破解。
/usr/local - 如果您还安装了其他软件，这可能会很危险。/opt/local，这应该是安全的。从头开始安装它，它应该可以工作。

好的，我做了mpapis的建议并消灭了rvm＆amp; amp;酿造，但我的一些酿造必须留下，所以我需要做： 酿造医生 然后 brew tap --repair homebrew / dupes
然后rvm install 1.8.7
在尝试获取服务器时，我遇到了以下问题：
