启动 Clojure 应用程序的 foreman 时出现问题

Question

我尝试按照在 Heroku 上获取 Clojure 应用程序的指南进行操作。除了在本地运行之外，一切正常。我使用的是 Windows 7。

该步骤显示：

1. gem install foreman
2. foreman start

On 1 我必须是管理员，但安装正常

当我执行 2 时，我得到：

C:/Program Files (x86)/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- pty (LoadError)
        from C:/Program Files (x86)/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

        from C:/Program Files (x86)/Ruby192/bin/foreman:19:in `<main>'

我缺少什么？

当我运行 gem 环境时，我得到：

Answer 1

替换我的第一个答案，因为它完全不合时宜。

看起来 pty 是标准 Ruby 的一部分： http ://ruby-doc.org/stdlib/libdoc/pty/rdoc/index.html

但是，根据 这篇旧论坛帖子，看起来 Ruby 的 pty 需要一些在 Windows 上实现起来不太简单的东西，所以很可能它在 Windows 上不可用Windows此时也可以。
