如何修复Appium IOS模拟器脚本错误：/bin/sh-c xcrun--sdk iphonesimulator--show sdk版本？

我在Appium上运行iOS模拟器脚本时出现此错误。它不会在iOS模拟器上加载Safari浏览器，并使用此错误停止脚本。有人知道如何解决这个问题吗？谢谢

xcrun--sdk iphonesimulator--show sdk version

，我回到家后，我会试试看。谢谢回复。Jeremy，它返回了9.0版本。现在当我运行相同的脚本时，我得到了这个错误。命令失败：/bin/sh-c'/Applications/Xcode.app/Contents/Developer/usr/bin/instruments'-s devices我重新启动并重新运行脚本，它仍然显示命令失败：/bin/sh-c xcrun--sdk iphonesimulator--show sdk version。但我不知道为什么在多次尝试后，它以前会起作用。它看起来十分之一有效。有点不对劲。我不知道怎么修理它。有什么想法吗？
