如何在Windows中使用popen3库？

Question

我尝试了所有的代码(主要是popen或open gem)，所以像这样的帖子和博客- http://blog.bigbinary.com/2012/10/18/backtick-system-exec-in-ruby.html

C:/svn/ruby/lib/ruby/1.8/open3.rb:57:in `fork': fork() function is unimplemented on this machine (NotImplementedError)
        from C:/svn/ruby/lib/ruby/1.8/open3.rb:57:in `popen3'

示例代码-

require 'open3'
cmd = 'git push heroku master'
Open3.popen3(cmd) do |stdin, stdout, stderr, wait_thr|
  puts "stdout is:" + stdout.read
  puts "stderr is:" + stderr.read
end

我如何在这个老的Ruby1.8gem上工作？

Answer 1

Windows不能在open3上运行。=/

IO::popen是我能想到的最接近的东西。
