Error on 'foreman start' while following the Python/Flask Heroku tutorial

Followed all instructions. Get this error when running foreman start:

So, apparently foreman does not work on Windows, which was not mentioned in the Heroku tutorial. Hope they fix that.

@Rosarch - I was able to use foreman on windows, look at the answer at http://stackoverflow.com/questions/11434287/foreman-start-fails-on-windows-following-heroku-tuturial/11436332#11436332 , So I guess their support guys are not updated. – zenpoy Jul 11 '12 at 15:44
this answer is incorrect. foreman is a ruby app, so you need to install ruby first. see the link zenpoy provided. – changokun Aug 04 '13 at 20:15

I encountered a similar problem and solved it, I think it should solve your issue too (be sure to uninstall former installations of ruby as sometimes there are several installations of the same version). Here is the solution: Foreman start fails on Windows following Heroku tutorial
