'ruby -v' 显示没有安装 ruby 版本（rbenv），但 rbenv 医生显示一切绿色

Question

我已经在我的 ubuntu 18.04 服务器中安装了 rbenv 并将变量添加到 .bashrc

来自服务器的控制台：

mr2552@ip-10-5-121-225:~$ ruby -v

Command 'ruby' not found, but can be installed with:

snap install ruby  # version 3.0.1, or
apt  install ruby

See 'snap info ruby' for additional versions.
