Your RVM is installed in /usr/local/rvm- it's often called system installation, this requires that your user ubuntuwill be added to rvmgroup:
您的 RVM 安装在/usr/local/rvm- 通常称为系统安装，这需要将您的用户ubuntu添加到rvm组：
rvm group add rvm "$USER"
yes use $USERit will be replaced by your shell with your user name
是的，使用$USER它会被你的 shell 替换为你的用户名
then log out and log in, ensure with:
然后注销并登录，确保：
id
that your user is in rvmgroup,
您的用户在rvm组中，
finally just in case update permissions for RVM:
最后以防万一更新 RVM 的权限：
rvm fix-permissions

The solution by @mpasis might not work if you're installing rvmusing ubuntu_rvmas by default because of copy+pasteit'll be installed as root.
Try installing rvmwith without sudoor with curlas explained on rvm.io.
如果您默认rvm使用ubuntu_rvm 进行安装，@mpasis 的解决方案可能不起作用，因为copy+paste它将安装为root. 尝试按照rvm.io 上的说明rvm使用 withoutsudo或 with安装。curl
