Ruby on rails '；ruby-v'；显示未安装ruby版本（rbenv），但rbenv doctor显示所有内容为绿色

我已经在我的Ubuntu18.04服务器中安装了rbenv，并在.bashrc中添加了变量

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.
