Appium测试-- "Sdk 9.3不在simctl Sdk列表中“

Question

我是个linux迷，被迫做苹果的事，我对一切都很迷茫.

我试图为一个iPad应用程序运行一个测试套件，我一直收到这个错误："XCUITest错误: Sdk '9.3‘不在simctl列表中“。我知道这是一个缺失的依赖，我可能需要安装这个Sdk 9.3，但我真的不知道如何去做，谷歌根本没有帮助。

下面是日志跟踪：

Answer 1

我认为它就像打开Xcode，然后跳入首选项来下载旧操作系统的仿真器一样简单。Xcode 8涉及ios 10，Xcode 7.3.x涉及ios 9.3

您还可能需要检查您的appium吐露，以确保您不需要仅仅告诉它使用10.0而不是9.3。一个简单的grep在你的回购应该会帮助你找到

另一种解决方案是在https://developer.apple.com/download/上从苹果下载xcode 7.3.1，然后在安装xcode之后，确保从终端中选择xcode，如下所示：

xcode-select -switch /path/to/new/Xcode.app/Contents/Developer/

然后，当您运行测试时，它应该会找到旧版本。

Answer 2

转到Xcode>>Preferences>>Components>>iOS 10模拟器(或任何必需的版本)。现在单击“检查并安装”。这会将选定的iOS版本添加到simctl的列表中。
