PTY gem not found

Question

I have Ruby 1.9.3 installed on windows. When I try to require the gem the console outputs that the gem was not found:

require \'pty\'

Which

Answer 1

As far as I know, there is no PTY module implementation for Windows as they don't have pseudo-terminal capabilities.

Answer 2

Currently seems ruby is supporting 'pty' module out of the box so you don't have to install any gem: https://ruby-doc.org/stdlib-2.5.3/libdoc/pty/rdoc/PTY.html

Answer 3

You can try

gem install rubysl-pty

if target ruby version is 1.9.x, run gem command with appropriate -v option

gem install rubysl-pty -v 1.0.0

if you would like to use PTY on Windows, my best recommendation is to use cygwin. I am able to install and use this rubysl-pty on my Windows with cygwin yet with few limitations:

$ gem install rubysl-pty -v 1.0.0

Sample code:

# test.rb
require 'pty'
PTY.getpty("ls") { |i,o,pid| p i; p pid }

Output:

$ ruby test.rb
