When attempting to install gem I am getting following error
C:\xampp\htdocs\mg>gem install therubyracer
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...

I have tried adding this in Gemfile
gem 'therubyracer',
gem 'less-rails
Tried
gem uninstall libv8
gem install therubyracer -v=0.10.1
Everything above failed and therubyracer never installed.
