自从升级到Xcode 13后，我在Xcode上构建nativescript应用程序时收到错误

./.build_env_vars.sh: line 454: declare: UID: readonly variable

    raise KeyError(key)
KeyError: 'DEPLOYMENT_TARGET_CLANG_FLAG_NAME'

我看了看，我找到的答案都是与目标C有关的。
有没有人遇到过这个问题，并找到了解决方案？

解决方案是将NativeScript升级到6.5.5或更高版本，其中包含补丁。
如果您对技术细节感兴趣，或者来自其他项目，请继续阅读。
在Xcode 13.3及以上版本中，环境变量DEPLOYMENT_TARGET_CLANG_NAME和DEPLOYMENT_TARGET_CLANG_ENV_NAME不再存在。
您可以通过使用EFFECTIVE_PLATFORM_NAME手动确定这些值来解决这个问题：

platform = env("EFFECTIVE_PLATFORM_NAME")
if platform is "-iphoneos":
    flag = "-miphoneos-version-min"
    target = "IPHONEOS_DEPLOYMENT_TARGET"
elif platform is "-iphonesimulator":
    flag = "-mios-simulator-version-min"
    target = "IPHONEOS_DEPLOYMENT_TARGET"
elif platform is "-watchos"
    flag = "-mwatchos-version-min"
    target = "WATCHOS_DEPLOYMENT_TARGET"
elif platform is "-watchossimulator"
    flag = "-mwatchos-simulator-version-min"
    target = "WATCHOS_DEPLOYMENT_TARGET"
elif platform is "-appletvos"
    flag = "-mappletvos-version-min"
    target = "APPLETVOS_DEPLOYMENT_TARGET"
elif platform is "-appletvsimulator":
    flag = "-mappletvsimulator-version-min"
    target = "APPLETVOS_DEPLOYMENT_TARGET"
else:
    flag = "-mmacosx-version-min"
    target = "MACOSX_DEPLOYMENT_TARGET"

感谢https://github.com/NativeScript/ios-jsc/pull/1296的作者演示了这项技术。
