问题描述

我正在运行 Ruby ruby​​ 1.9.3p125，并且不断收到此错误，这使我无法在 Rails 中进行任何类型的开发.

I'm running Ruby ruby 1.9.3p125 and I keep getting this error which is making it impossible for me to do any kind of development in Rails.

您的 ruby​​ 安装似乎缺少 psych(用于 YAML 输出).到消除此警告，请安装 libyaml 并重新安装您的红宝石.

我在 Google 上四处搜索并尝试了所有方法，但似乎没有任何效果.我真的很想开始一些新项目，但似乎无法绕过这个障碍.

I've Googled around and tried seemingly everything but nothing seems to be working. I'm really eager to start on some new projects but can't seem to get around this hurdle.

推荐答案

我在使用 rvm 安装 ruby​​ 1.9.3 后遇到了同样的问题.我通过将 yaml-0.1.4.tar.gz 下载到 ~/.rvm/archives 然后重新安装 ruby​​ 来解决它.

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 

如果你得到一些编译错误，试试这个

If you get some compileerrors, try with this instead

rvm reinstall 1.9.3 --with-gcc=clang
