How to properly use yeoman generator-jekyllrb under Windows?

Question

Windows

Installed node v0.10.29 , npm 1.4.14, ruby ​​1.9.3p545, ruby ​​DevKit, Python 2.7.7, yeoman 1.2.1.
I want to run generator-jekyllrb. By itself, jekyll works fine.
The generator itself is installed, apart from a bug with grunt-contrib-imagemin, which has been fixed.
But when I try to grunt serve I get an error

Jekyll output:
Configuration file: _config.yml
Configuration file: _config.build.yml
            Source: app
       Destination: dist
