请确保您已经安装了 ruby​​ 的依赖项。
https://github.com/rbenv/ruby-build/wiki#suggested-build-environment

sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm6 libgdbm-dev libdb-dev

不同的 Ubuntu 版本中可能缺少某些库。
就我而言，在 Ubuntu 18.04 上找不到 libgdbm6
