Answer 1

将其添加到〜/ .bashrc文件的底部：

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

如果不起作用，请尝试：

[[ -s "/home/yourusername/.rvm/scripts/rvm" ]] && source "/home/yourusername/.rvm/scripts/rvm"

Answer 2

Terminal - ＆GT; Edit - ＆GT; Profile Preferences - ＆GT; Title and Command - ＆GT; Run command as a login shell

Answer 3

我猜你需要编辑你的终端设置

试试吧 https://beatreader.wordpress.com/2016/08/09/ruby-on-rails-problemmissing-after-reboot/ 要么每次打开终端

时都需要运行此代码

source "$HOME/.rvm/scripts/rvm"

重启后，当前未安装rails
