更新后，Calabash iOS不会运行

Question

在上次卡拉巴斯更新之后，我无法再运行测试了。我用：

• calabash-cucumber-0.10.2
• 运行回路-1.0.8
• ruby-2.1.0
• Xcode 6.0.1
• 和Xamarin Calabash组分(Xamarin测试云代理10.1.1)

当我尝试运行测试时，我得到：

undefined method `[]' for nil:NilClass (NoMethodError)
  /Users/user/.rvm/gems/ruby-2.1.0/gems/run_loop-1.0.8/lib/run_loop/sim_control.rb:688:in `enable_accessibility_in_sim_data_dir'

在"calabash-ios sim acc“或"calabash-ios console”中，当我试图运行start_test_server_in_background时，我会得到相同的错误。任何帮助都是非常感谢的。
