Estou tentando reinstalar o Ruby na minha máquina Ubuntu 14.04, mas estou confuso sobre como preciso configurar minha variável PATH ou outras coisas. Quando eu tento como usuário normal, recebo todos os tipos de erros de permissão negada ...
myuser@myproject:~$ rvm reinstall ruby-2.4.0

mas quando eu tento e instalo como sudo, recebo o erro "comando não encontrado"
myuser@myproject:~$ sudo rvm reinstall ruby-2.4.0
sudo: rvm: command not found
Como configuro meu sudo para que ele encontre meu executável rvm da mesma forma que meu usuário normal pode?
Experimente sudo -E rvm reinstall ruby-2.4.0 .
De man sudo :
-E, --preserve-env
Indicates to the security policy that the user wishes to preserve their existing environment variables. The security policy may return an error if the user does not have permission to preserve the environment.
