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


the problem following.

error installing libv8: error: failed build gem native extension.      d:/ruby193/bin/ruby.exe extconf.rb     creating makefile     system can not find specified path          d:ruby193/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.17/ext/libv8/builder.rb:49:in'setup_python!':libv8 requires python 2 installed in order build,but not available (runtimeerror)              d:ruby193/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.17/ext/libv8/builder.rb:35:in 'block in build_libv8!'              d:ruby193/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.17/ext/libv8/builder.rb:34:in 'chdir'              d:ruby193/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.17/ext/libv8/builder.rb:34:in 'build_libv8!'              d:ruby193/lib/ruby/gems/1.9.1/gems/libv8-3.11.8.17/ext/libv8/builder.rb:34:in 'install!'              extconf.rb:7: in '<main>' have installed python27 , add path.  python --version python 2.7.4

then check code following.

 def setup_python!       # if python v2 cannot found in path,       # create symbolic link python2 current directory , put       # @ head of path. way commands inherit environment       # use ./python -> python2       if python_version !~ /^2/         unless system 'which python2 2>&1 > /dev/null'           fail "libv8 requires python 2 installed in order build, #{python_version}"         end         `ln -fs #{`which python2`.chomp} python`         env['path'] = "#{file.expand_path '.'}:#{env['path']}"       end     end

i tried install linux command line windows 'ln -fs' should working.but problem still can not solved.

try this:

gem install libv8 -v '3.11.8.17' -- --with-system-v8

this error pain untill run above command :)
