我已经安装了新版本的 ruby​​ - 1.9.3-p125，然后我遇到了 pry 的问题

我试图通过这篇文章解决这个问题，但在make命令之后我得到了答案

Nothing to be done for `all’

如何解决这个问题？谢谢

嘿 megas 你安装了 lncurses 吗？如果不尝试：

sudo apt-get install libncurses5-dev libreadline5-dev

从this Blogpost中得到它似乎与您的问题有一些相似之处。

解决方案：

rvm uninstall 1.9.3-p125
sudo apt-get install libreadline-dev
rvm install 1.9.3-p125 --with-readline-dir=/usr/include/readline
