我通过 CocoaPods 将 EarlGrey 添加到我的 iOS 项目中。我创建了新目标，如下所述：https ://github.com/google/EarlGrey/blob/master/docs/install-and-run.md 。
我的问题是，按照此说明，简单的 EarlGrey 快速测试被错误解释，并导致构建错误
有没有人遇到过这样的问题？有什么我可以解决的吗？
由于我是 iOS/EarlGrey 的新手 - 请随时向我提出任何我可以添加到这个问题以使其更具体的建议。

执行命令后gem install earlgrey会pod install出现以下错误：
RuntimeError - Test target group not found!
