How to debug Middleman 3 gem installation issues on Windows. - ruby

Question

I have installed Middleman 3.1.5 as described on my Windows 8 Machnine along with Ruby using rubyinstaller-2.0.0-p247.exe and followed the steps to get started with success. I am now building my first site with some success (coding some pages, starting the server, building the site) but when I try to use some advanced third party components like middleman-navigation or middleman-deploy I seem to hit a wall. At first I thought of a mistake by myself but as more and more things seem to be buggy I want to figure out what is wrong with my setup or at least confirm nothing is.
Some example output that seems buggy to me:
$ middleman help
WARN: Unresolved specs during Gem::Specification.reset:
rack (>= 1.0, >= 1.4.5)
thor (< 2.0, >= 0.15.2)
activesupport (~> 3.2.6)
listen (~> 1.2.2)
i18n (~> 0.6.1)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
Tasks:
...
When i try to install middleman-deploy as described, adding gem "middleman-deploy" to my Gemfile and run bundle install there is no indication that anything changed:
$ bundle install

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
I then add a configuration to config.rb and try to use the gem without success:
$ middleman deploy
WARN: Unresolved specs during Gem::Specification.reset:
rack (>= 1.0, >= 1.4.5)
thor (< 2.0, >= 0.15.2)
multi_json (~> 1.0)
rb-inotify (>= 0.9)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
There's no 'deploy' command for Middleman. Try 'middleman help' for a list of commands.
Please help me to narrow down the cause of these issues.

Answer 1

I had a similar WARN: Unresolved specs during Gem::Specification.reset: message when I did middleman build I'm on a Mac using rvm with ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.3.0]. I found an issue post on GitHub with a similar WARN and the fix was to run gem regenerate_binstubs. It cleared the WARN for me. I'm not sure exactly what that does but it clears up a few issues with rubygems-bundler.
