在mac osX上安装libyaml for ruby​​(Lion)

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!

Answer 1

目前的发布[是] LibYAML:0.1.4 (2011-05-30)[2012年我回答了这个问题].

下载源包: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

$ make

$ make install

要不就:

$brew install libyaml

下一个, $brew install ruby

祝好运.

尝试这个...

打开一个新的终端窗口并：

cd .rvm/src
sudo rm -rf yaml*

（提供您的凭据）

cd ~
rvm pkg install libyaml
