在 Lion 上使用 RVM 将 1.9.2p180 升级到 1.9.3 时出错

Question

运行以下命令时出现此错误：

$ rvm upgrade 1.9.2-p180 1.9.3-p0

当我跟踪日志时，我得到以下输出：

installing default stringio libraries
installing default strscan libraries
installing default syck libraries
installing default syslog libraries
linking shared-object tcltklib.bundle
ld: in /usr/local/lib/libiconv.2.dylib, missing required architecture x86_64 in file for architecture x86_64

make[1]: *** [ext/tk/all] Error 2
make: *** [build-ext] Error 2

关于如何继续前进的任何想法？

Answer 1

这为我解决了这个问题。

rm /usr/local/lib/libiconv.2.dylib
ln -s /usr/lib/libiconv.2.dylib /usr/local/lib/libiconv.2.dylib

也保留了我的 XCode 4.2...

Answer 2

从消息来看，您的 iconv 未针对 x86_64 进行编译。

检查rvm 注释 和rvm 要求，看看它们是否能更清楚地说明问题。
