导读：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... yeschecking for readline/readline.h... yeschecking for readline/history.h... yeschecking

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？

解决方法

同样的问题在这里 Readline errors prevent me running rails console

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}.
