错误的X平台蠡

开始自动启动的iOS当我运行测试，我写在控制台以下错误：错误的X平台蠡

undefined method `split' for nil:NilClass (NoMethodError)

测试本身就是从这里开始的example。下面是错误的一个代码：

3210

运行以下命令：bundle exec cucumber -p ios DEVICE_TARGET="6D45E1...6513"

谁能遇到？

你可以包含导致上述错误的代码？ –

@ChuckvanderLinden添加代码 –

DEVICE_TARGET UUID是否确实存在于可用模拟器列表中？ instruments -s会显示设备。切换Xcode版本并且不重新启动或重新启动CoreSimulator服务可能导致找不到模拟器。

DEVICE_TARGET UUID实际上是 –

看起来像这样的代码sdk_version = elm[/(\d\.\d(\.\d)? Simulator)/, 0]没有返回任何东西。看起来你期待它返回一个字符串。我会在该区域进行调试。

错误是告诉你，你的选择导致了一个无对象，当然没有类，也没有.split方法。因此，试图调用.split方法的结果是给出了错误信息，即您没有定义.split方法。
