我安装了新版本的 ruby - 1.9.3-p125，然后我遇到了 pry 问题

我尝试通过此 article 来解决此问题但在 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

最佳答案
嘿，你安装了 lncurses 了吗？如果没有尝试:
sudo apt-get install libncurses5-dev libreadline5-dev
从这里得到的Blogpost这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
