`rbenv rehash` not generating shims (using rbenv-gemset plugin)

I'm using rbenv and rbenv-gemset to manage the gems for a middleman project.

Even though I've run the rbenv rehash command, the shim for middleman does not exist:

→  middleman git:(master) × rbenv which middleman
rbenv: middleman: command not found

You can see here that I do have the middleman gem installed though:

→  middleman git:(master) × gem list middleman

*** LOCAL GEMS ***

middleman (3.1.5)
middleman-core (3.1.5)
middleman-more (3.1.5)
middleman-sprockets (3.1.4)

And here it is in my rbenv-gemset directory:

→  middleman git:(master) × ls .gems/gems
middleman-3.1.5
middleman-core-3.1.5
middleman-more-3.1.5
middleman-sprockets-3.1.4

And here you can also see there is a middleman command in the rbenv-gemsets directory:

→  middleman git:(master) × ls .gems/bin/
bundle       erubis       kramdown     padrino      rails        rake2thor    ri           sass-convert sprockets    tilt
compass      haml         middleman    rackup       rake         rdoc         sass         scss         thor         tt

Yet running rbenv rehash does not generate the middleman shim (among others) :

→  middleman git:(master) × ls ~/.rbenv/shims
bundle          dnsimple.rb     gem             rackup          rdoc            sass            sdoc            testrb          tt              update_rubygems
compass         erb             httparty        rails           ri              sass-convert    sdoc-merge      thor            unicorn
dnsimple        erubis          irb             rake            ruby            scss            sprockets       tilt            unicorn_rails

Here is my gem environment:

→  middleman git:(master) × gem env

What could be going wrong? Is this an issue with rbenv or rbenv-gemset?

Solution

funnily enough, somebody reported the exact same problem just a few days ago - and with middleman too. The problem has now been fixed (see https://github.com/jf/rbenv-gemset/issues/48). The problem in this case was rbenv-gemset. Sorry about that!

You can upgrade to the latest version of rbenv-gemset to get the fix (are you using git? or homebrew?)

EDIT @asgeo1, you might want to "accept" that answer, so that others who come by will be helped as well. Thanks.
