By orip:

Most of these themes used to work without using rvm (or rbenv or the rbenv plugin) at all, because the ruby path string was just an empty string.
Now they fail with #878:

command not found: rbenv_prompt_info

Perhaps provide an empty `rbenv_prompt_info` using something like this?

functions rbenv_prompt_info >& /dev/null && rbenv_prompt_info() {}
