我认为命令二进制文件可能不在路径上，所以尝试搜索它但没有运气..！！
sudo find /usr/ -iname readline
basically I'm trying to install http://freecode.com/projects/rlwrap/and the configure is failing saying readline library is not found.
基本上我正在尝试安装http://freecode.com/projects/rlwrap/并且配置失败，说没有找到 readline 库。

"readline" is not a command.
“readline”不是命令。
If you are trying to build software that uses the readline library then you need to install readline-devel.
如果您正在尝试构建使用 readline 库的软件，那么您需要安装readline-devel.
