Windows puma unable to load application due to backports Bad File descriptor

Question

I'm trying to run a puma project on my Windows 8 machine and keep getting this error whenever I try to run bundle puma exec -p 4567 I get an error about a Bad file descriptor in part of the backports code.

PS C:\Users\andrew\work\test> bundle exec puma -p 4567

I'm using ruby 2.0.0p576 (2014-09-19) [i386-mingw32] DevKit-mingw64-32-4.7.2-20130224

I was able to successfully run install (had to install the ssl headers to get it to work), but I keep getting this error when I try to deploy the puma server. I'm pretty new to ruby development, so I'm unsure what other things I could look into or how to resolve the EBADF error in a gem.

Thanks!

This is fixed in the latest release of Backports (3.6.1) per issue 86. Either require 3.6.1 or go back to p481
