ruby update with rvm error message (rvm requirements fails) - ruby

Question

I am new to ruby and I am trying to update to the latest stable version of ruby using rvm. I get the following error message:

As far as I know I have rvm and homebrew installed. The following command line gives a completely different message.

Sorry if its long but I can't find the answer anywhere. Thanks.

Answer 1

The following command line gives a completely different message.
Here are the error messages:
First error message:
Failed to update Homebrew, follow instructions here:
https://github.com/Homebrew/homebrew/wiki/Common-Issues
and make sure brew update works before continuing.\n'
Second error message:
Failed to update Homebrew, follow instructions here:
https://github.com/Homebrew/homebrew/wiki/Common-Issues and make sure brew update works before continuing.\n'
So it looks like it's an installing homebrew problem. I would think that going to the link given, and reading about the common issues encountered when updating homebrew would be something to try.

Answer 2

I had the same issue, did you try to run it with sudo?
sudo rvm install ruby-2.1.2
