error when run rvm requirements

Question

I followed this tutorial to install rvm on ubuntu 12.04 when run rvm requirements, I got the following message

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'.

I got same message when run rvm install 1.9.3

Can anyone help?

Thanks.

Sometimes the official documentation it's more reliable than a blog. Take a look at the rvm documentation. The command from the blog to install rvm is:

curl -L get.rvm.io | bash -s stable

and the official documentation recommend that one:

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

Probably this will solve your problems with autolibs, the same that was happening for example in that question .
