[color=darkred]Update: 2012/03/27[/color] 当前版本ruby1.9.3p135 ubuntu 11.10 解决办法先试试

rvm requirements #先安装依赖的包 rvm remove 1.9.2 rvm install 1.9.2

遇到问题是rvm use用不了，其他都能用，提示 [quote]RVM is not a function, selecting rubies with 'rvm use ...' will not work.[/quote] 是一个所谓的“Run as login shell”问题，官方有介绍[url]https://rvm.beginrescueend.com/integration/gnome-terminal/[/url] 实际设计多用户登录什么的问题，就是把如下放到.bashrc,不要放到其他什么bash_profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

source ~/.bashrc

问题现象就是 [quote] Readline was unable to be required, if you need completion or history install readline then reinstall the ruby. You may follow 'rvm notes' for dependencies and/or read the docs page https://rvm.beginrescueend.com/packages/readline/ . Be sure you 'rvm remove X ; rvm install X' to re-compile your ruby with readline support after obtaining the readline libraries. [/quote] 标准的解决办法是 [url]https://rvm.beginrescueend.com/packages/readline/[/url] 问题是我一进行到这一步就有问题

$ cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline $ ruby extconf.rb -- --with-readline-dir="$HOME/.rvm/usr"

[quote]checking for tgetnum() in -lncurses... yes checking for readline/readline.h... yes checking for readline/history.h... yes checking for readline() in -lreadline... no [/quote] 后来发现两个问题： 1. 路径

ruby extconf.rb -- --with-readline-dir='/home/ra/.rvm/usr/include/readline'

一个是没有装

sudo aptitude install libreadline-dev sudo aptitude install libreadline5-dev libncurses5-dev

够新的呢要换6

sudo aptitude install libreadline6-dev

1.9.3参考

rvm pkg install openssl #older format - rvm package install openssl rvm pkg install iconv #older format - rvm package install iconv rvm pkg install readline#rails console缺少的lib rvm remove 1.9.3 rvm install 1.9.3 -C --with-openssl-dir=\$HOME/.rvm/usr,--with-iconv-dir=\$HOME/.rvm/usr, --with-readline-6.2-dir=\$HOME/.rvm/usr rvm 1.9.3 --default

还是ubuntu的readline error [quote]undefined symbol: UP[/quote]

ls /usr/local/lib su mkdir temp mv /usr/local/lib/libreadline* temp ldconfig apt-get update rm -rf /usr/local/lib/temp
