我按照
本教程
在运行时在ubuntu 12.04上安装rvm rvm requirements,我收到以下消息
Installing requirements for ubuntu, might require sudo password.
Running 'apt-get --quiet --yes update' would require sudo.
Cowardly refusing to continue, please read 'rvm autolibs'.
Updating repositories
Missing required packages: libgdbm-dev, libffi-dev.
Cowardly refusing to continue, please read 'rvm autolibs'.
跑步时我得到了同样的信息 rvm install 1.9.3
有人可以帮忙吗？
谢谢.
