我试图安装Ruby Version Manager(RVM)失败。如何解决我遇到的这个错误？
ubuntu@ip-172-31-0-20:/tmp$ rvm install ruby-1.9.3-p484
Searching for binary rubies, this might take some time.

Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

最佳回答
您的RVM安装在/usr/local/rvm中-通常称为系统安装，这要求将您的用户ubuntu添加到rvm组中：
rvm group add rvm "$USER"
是的，使用$USER，它将用您的用户名替换为您的shell。
然后注销并登录，请确保：
id
您的用户属于rvm组，
最后以防万一RVM的更新权限：
rvm fix-permissions
