since a while I am trying to install the less-rails gem on my windows7 machine.
I already managed to install the needed therubyracer.gem using this binary file: htt
gem install therubyracer*
bundle install
Have fun.
After a lot of research and trial and error it seems that less is not working on the windows plattform at the moment.
So my solution is to use the bootstrap-sass-rails gem instead. This is working pretty well.
