似乎您的ruby安装缺少心理功能(用于YAML输出).到 消除此警告，请安装libyaml并重新安装 红宝石.

推荐答案

用rvm安装ruby 1.9.3之后，我遇到了同样的问题. 我通过将 yaml-0.1.4.tar.gz 下载到〜/.rvm/archives中，然后再次重新安装ruby来解决该问题.

I had same problem after installing ruby 1.9.3 with rvm. I solve it by downloading yaml-0.1.4.tar.gz into ~/.rvm/archives and then reinstalled ruby again.

cd ~/.rvm/archives
wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
rvm reinstall 1.9.3 

如果遇到一些编译错误，请尝试使用此方法

If you get some compileerrors, try with this instead

rvm reinstall 1.9.3 --with-gcc=clang
