昨天拿到一个服务器， 很奇怪，根据源代码编译，安装之后，总是提示 psych 错误（It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. ) 而且搞了几次都没解决问题。后来考虑到这个SERVER还要兼容1.8.x 系列，我就使用RVM吧！ ( yesterday when I was setting up the environment of my Rails on ubuntu server by download-compile-make install the ruby source code, there's always an error message : ".. missing psych (for YAML output ) "... ) after diving into this problem but not solved it in some time, also considering the compatibility for other Ruby versions, I decided to install RVM instead. )
步骤： (steps)
1. 安装rvm （略） (install RVM )
2. $ rvm requirements ( then install all the needed libs )
(?)2. $ rvm pkg install libyaml
(?)3. $ rvm pkg install readline --verify-downloads 1
(?)4. $ rvm pkg install {iconv,zlib,openssl}
5. $ rvm install 1.9.3 -C --with-openssl-dir=$HOME/.rvm/usr, --with-iconv-dir=$HOME/.rvm/usr
