ubuntu10.04安装ruby提示Missing required packages: libgdbm-dev, libffi-dev.

一个是用rvm安装ruby的时候，出现

Ruby

1 2 3 4 5 6

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'.

解决方法是

Ruby

1	\curl -L https://get.rvm.io | bash -s stable --autolibs=3 --rails

还有一个问题是装完rails之后执行 -v时 出现

Ruby

1	The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails

解决方法是

set the ‘Run command as login shell’ checkbox on the Title and Command tab inside of gnome-terminal’s Settings page.
