我在 Mac Mini 上的 Rubymine IDE 中使用 rspec 成功创建了一些 calabash-ios 测试，效果很好；
但是最近我搬到了 iMac，因此不得不配置和安装 ruby 和必要的 gem。但是，这次由于以下错误我无法执行我的测试并且我被卡住了。（复制下面的错误消息）
最好的猜测是这与两台机器上 gem 的版本不同有关。我进行了详细的版本比较，观察到了很多差异.. 在这里列出我认为可能与此错误相关的那些：（不幸的是，我现在无法安装旧版本的 gems（在 iMac 上），因为它们不再存在，而是更新版本）
以 Gem 名称的形式列出的 tge 版本= OldMachine 上的版本 && NewMachine 上的版本
CFPropertyList = 2.2.0 && 2.2.1
httpclient = 2.3.3 && 2.3.4.1
rspec = 2.14.1, 2.9.0.rc2 && 2.14.1
rspec 核心 = 2.14.4、2.14.3、2.9.0.rc2 && 2.14.5
rspec-expectations = 2.14.1, 2.14.0, 2.9.0.rc2 && 2.14.2
rspec-mocks = 2.14.3, 2.14.2, 2.14.1,2.9.0.rc2 && 2.14.3
rubygems 更新 = 2.0.6、2.0.5 && 2.0.7
有没有其他人遇到过更新版本的 gems 的任何问题？
请分享任何可以帮助我尽快解决此问题的建议。有没有办法移动到旧版本的 gems 并检查测试是否正常工作？
或者您还有什么可以考虑并建议我尝试运行测试的吗？
我确认我的防火墙已关闭
