看来问题不在于rbenv其他版本管理器，例如chruby和asdf。真正的问题是 openssl 和 ruby​​ 2.3.x 的兼容性问题。

2.4之前的Ruby版本的openssl扩展与OpenSSL 1.1.x不兼容。目前，大多数附带 OpenSSL 1.1.0 的 Linux 发行版都有一个单独的 OpenSSL 1.0.x 软件包。

您需要安装早期版本的 OpenSSL 或使用 ruby​​ 2.4.x。

sudo apt-get install autoconf bison build-essential libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev libdb-dev


sudo apt-get install libssl1.0-dev

这解决了我的问题。

笔记：

libgdbm5适用于 Ubuntu19 或 Mint19 及libgdbm6更高版本。
