`rails s` says "`require': cannot load such file -- pty (LoadError)" in Windows RailsInstaller

I have just installed RailsInstaller on my Windows 10 PC. I am not able to run rails s or rails g controller StaticPages home help.

I have also tried to fix this by installing the zeus gem as suggested by this related StackOverflow question but had no success.

Gemfile:

source 'https://rubygems.org'

gem 'rails',        '4.2.2'
gem 'sass-rails',   '5.0.2'
gem 'uglifier',     '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks',   '2.3.0'
gem 'jbuilder',     '2.2.3'
gem 'sdoc',         '0.4.0', group: :doc
gem 'pry-nav', group: [:development, :test]

group :development, :test do
  gem 'sqlite3',     '>= 1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

Errors:

Solution

  • The backtrace tells us that the web-console gem wants Ruby's pty library. Unfortunately PTYs (pseudo-terminals) are a Unix/Linux feature which does not exist on Windows, so that Ruby library doesn't either.

    You can get moving in a couple of ways:
