尝试以 sudo 身份运行 rvm 命令时出现“找不到命令”

尝试以 sudo 身份运行 rvm 命令时出现“找不到命令”

我正在尝试在 Ubuntu 14.04 机器上重新安装 Ruby,但我对如何设置 PATH 变量或其他内容感到困惑。当我以普通用户身份尝试时,我收到各种权限被拒绝的错误......

myuser@myproject:~$ rvm reinstall ruby-2.4.0

但是当我 tyr 并安装为 sudo 时,我收到“命令未找到”错误

myuser@myproject:~$ sudo rvm reinstall ruby-2.4.0
sudo: rvm: command not found

如何设置 sudo 以便它像普通用户一样找到我的 rvm 可执行文件?

答案1

尝试sudo -E rvm reinstall ruby-2.4.0

man sudo

-E, --preserve-env

向安全策略表明用户希望保留其现有的环境变量。如果用户没有保护环境的权限,安全策略可能会返回错误。
