Unable to install libv8 3.11.8.17 in Rails on Windows

Cannot install libv8 3.11.8.17 gem. I already looked around and found out that it does not support Windows. Although I'm still looking for a workaround?

Make sure that `gem install libv8 -v '3.11.8.17'` succeeds before bundling.

I am not trying to use therubyracer, and honestly do not know which stone depends on libv8. Installing Python27 and installing PATH did nothing. Anything I can do except change platforms? Or maybe there is a workaround with v8.dll available from https://github.com/hiranpeiris/therubyracer_for_windows that I don't seem to understand?

try it

 gem install libv8 -v '3.16.14.3' -- --with-system-v8

I use libV8 and TheRubyRacer for prod only in my Linux environment. I share them in the gemfile:

 group :production do gem 'libv8', '~> 3.11.8.3' gem 'therubyracer', :platform => :ruby end

Then I will bind the installation without production:

 bundle install --without production

(See SO article: Why does “bundle” install production stones on my development machine? )

This does not seem to allow discussing all of V8 on Windows.
