ruby - 在 mac osX (Lion) 上为 ruby​​ 安装 libyaml

Question

我收到此错误消息:

"It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby."

我试过输入这个命令:rvm pkg install libyaml

我收到此错误消息:

"Fetching yaml-0.1.4.tar.gz to /Users/luke/.rvm/archives
Extracting yaml-0.1.4.tar.gz to /Users/luke/.rvm/src
Error running 'tar xmzf /Users/luke/.rvm/archives/yaml-0.1.4.tar.gz -C

有谁知道我做错了什么？谢谢!

当前版本 [是] LibYAML:0.1.4 (2011-05-30) [2012 年我回答这个问题时]。

下载源码包:http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz。

要构建和安装 LibYAML，请运行

$tar zxf yaml-0.1.4.tar.gz

$cd yaml-0.1.4

$ ./configure

$制作

$ make install

或者只是:

$brew 安装 libyaml

接下来，$brew 安装 ruby​​

祝你好运。
