我在我的ubropu 11.10上使用rvm.我的readline不工作,我尝试
ruby extconf.rb但它没有通过.输出如下：
- $ruby extconf.rb
- checking for tgetnum() in -lncurses... yes
- checking for readline/readline.h... yes
- checking for readline/history.h... yes
- checking for readline() in -lreadline... no
- checking for readline() in -ledit... no
- checking for editline/readline.h... no
我试过安装libncurses5-dev&中的libreadline5-dev的
- $sudo apt-get install libncurses5-dev libreadline5-dev
- Reading package lists... Done
- Building dependency tree
- Reading state information... Done
- Package libreadline5-dev is not available,but is referred to by another package.
- This may mean that the package is missing,has been obsoleted,or
- is only available from another source
- However the following packages replace it:
- libreadline-gplv2-dev:i386 lib64readline-gplv2-dev:i386 libreadline-gplv2-dev
- E: Package 'libreadline5-dev' has no installation candidate
这里有什么问题？谁能帮忙？

在ubuntu下,您可以使用系统readline安装.
- rvm uninstall ${YOURUBYVERSION}
- sudo apt-get install libreadline-dev
- rvm install ${YOURUBYVERSION} --with-readline-dir=/usr/include/readline
用您所需的红宝石版本代替${YOURUBYVERSION}.
