Your bundle is locked to rest_client (1.8.1), but that version could not be
found in any of the sources listed in your Gemfile. If you haven't changed
sources, that means the author of rest_client (1.8.1) has removed it. You'll
need to update your bundle to a version other than rest_client (1.8.1) that
hasn't been removed in order to install.

I wanted to try the sandbox version but everytime I try to bundle install I get the error on top.
