I'm running on windows 8.1 and try to run 'middleman server' (with gem version 2.4.8 and Middleman version 3.3.12). When doing so I get the following error (see below appendix for full error message): " You have already activated listen 3.0.3, but your Gemfile requires listen 2.10.1"
Yet the gem 'Listen' is not explicitely written in my gemfile, must be a dependency with something else.
So what I did was to explicitely add in my gemfile :
gem 'listen', '~> 2.10.1'
And then run again
$bundle install
Yet when I run again '$middleman server' it does not work. So in my terminal I check which version of 'listen' gem I have and see that it's :
C:\Users\Edouard\Desktop\stylus>bundle show listen
C:/Ruby22/lib/ruby/gems/2.2.0/gems/listen-2.10.1
Would someone have a lead on how to solve that ? Because I don't have a clue..
Appendix - The whole error message I get is :

The issue is apparently linked to the gem middleman-deploy on windows 8.1. Here is the solution I apply using github :
remove middleman-deploy from gemfile
in the same folder than the gemfile create a rakefile (without any extension) on which you put require 'middleman gh-pages'
then after you made some changes to your work, do a commit on master branch
then do rake publish
