我已经在我的 Mac（运行 OSX 10.8.2）和 PC（运行 Windows 7）上安装了 ruby（1.9.3）。我已经安装（使用“gem install ...”）net-ssh、test-unit、mocha 和 echoe。安装看起来很干净（Mac 抱怨文档中有一些 unicode 垃圾，但我不在乎）。
当我运行发行版中包含的单元测试时，我遇到了失败和错误。它们在 Mac 和 PC 上是不同的。据我所知，我有必要的东西——ssh 正在工作，我的 .ssh 目录存在并且有一个 id_dsa 对和一个 id_rsa 对。
很长一段时间以来，我一直在使用 SSH（shell、sftp、scp 等）与我的 mac 进行连接，所以我认为我的 SSH 堆栈正在工作。
这是一个愚蠢的配置问题，还是 net-ssh/Ruby 中有问题？
在 Mac 上，我通过运行 net-ssh 测试套件得到以下结果：
tms-mac:test tms$ ruby -Ilib -Itest -rrubygems test_all.rb
*** Mocha deprecation warning: Change `require 'mocha'` to `require 'mocha/setup'`.
