Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.  Check the mkmf.log file for more details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

Checking for Python... Unable to build libv8: Python not found! 

So I can't complete "bundle install".

Answer 1

Install ActivePython version 2.7.2.5, then run:

gem install libv8 --version 3.11.8.0

to install the libv8 in Windows, the latest version 3.11.8.3 can not work in windows, but 3.11.8.0 can in Windows 7.

Answer 2

On windows 7, with ruby193 I installed python27, I added to the PATH variable the python's folder, I wrote gem install libv8 in the console and libv8 was succesfully installed
