How to get Rspec test in Colour for windows on MINGW

I'm new to Ruby, just tying to learn it, following the Ruby on Rails Tutorial

I'm running the GitBash MINGW for window, and when I run (rspec 2.4.0)

rspec spec/

I get the response:

You must use ANSICON 1.31 or later (http://adoxa.110mb.com/ansicon/) to use 
colour on Windows

.开发者_C百科.. but I quite like using MINGW. and if I use ANSICON I cant seem to get

ssh-add 

to work, I get the error

Could not open a connection to your authentication agent

I could use MINGW for Pushing and ANSICON for Testing, but I'd rather have it all in the one console.

Since GitBash already supports escapes, you should be able to fake RSpec/Ruby by defining the ANSICON environment variable. Not sure if Ruby actually reads it, but its content is "WxH (wxh)", where W & H are the width & height of the buffer and w & h the window.
