gem install libv8 --version '3.11.8.17' on ruby (windows)

Question

The problem is as following.

Error installing libv8:
ERROR: Failed to build gem native extension.

    D:/Ruby193/bin/ruby.exe extconf.rb
    creating Makefi         


        

Answer 1

I could be reading this wrong, but I think the problem is this line:

unless system 'which python2 2>&1 > /dev/null'

It's looking for python2 when in fact the command for python is simply python.

Perhaps try aliasing python to python2.
