To quote from the website
[[https://github.com/purcell/exec-path-from-shell]]:

,----
| Motivation
| 
| Ever find that a command works in your shell, but not in Emacs?
| 
| This happens a lot on OS X, where an Emacs instance started from the GUI
| inherits a default set of environment variables.
| 
| This library works solves this problem by copying important environment
| variables from the user's shell: it works by asking your shell to print
| out the variables of interest, then copying them into the Emacs
| environment.
| 
| Compatibility
| 
| If you use a non-POSIX-standard shell such as tcsh or fish, your shell
| will be asked to execute sh as a subshell in order to print out the
| variables in a format which can be reliably parsed. sh must be a
| POSIX-compliant shell in this case.
| 
| Note that shell variables which have not been exported as environment
| variables (e.g. using the "export" keyword) may not be visible to
| `exec-path-from-shell'.

Maybe this helps you? I have never used anything different than bash and
never Ruby - so I can't help you there.

Cheers,

Rainer
