如何将 ruby​​ 版本更新到 2.5.1？

Question

当我尝试通过以下方式打开 metasploit 时

msfconsole

它显示了一个错误

rbenv: version `2.5.1' is not installed (set by /opt/metasploit-framework/.ruby-version)

我试过

rbenv install rbx-2.5.1

它的显示

BUILD FAILED (Ubuntu 16.04 using ruby-build 20160602-19-g0c35180)

现在做什么？

尝试运行这个命令：

$ sudo apt-get i
$ sudo apt-get install libbison-dev bison

然后，再试一次。
