错误:无法为目标'arm64-apple-ios10.0-simulator'加载标准库？

错误:无法为目标'arm64-apple-ios10.0-simulator'加载标准库？

我更新了我的Xcode但无法构建.它失败了:

<unknown>:0: error: unable to load standard library for target 'arm64-apple-ios10.0-simulator'

合并脚本:

 # 1
# Set bash script to exit immediately if any commands fail.
set -e

# 2
# Setup some constants for use later on.
FRAMEWORK_NAME="SDK"
OUTPUT_PATH="${SRCROOT}"

# 3
# If remnants from a previous build exist, delete them.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"
fi

# 4
# Build the framework for device and for simulator (using
# all needed architectures).
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch 
arm64 -arch armv7 -arch armv7s only_active_arch=no defines_module=yes - 
sdk "iphoneos"
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch 
x86_64 -arch i386 only_active_arch=no defines_module=yes -sdk 
"iphonesimulator"

实际上通过选择Generic iOS Device何时构建而不是模拟器设备来解决这个问题.

编辑:我应该提到,在Xcode 10中.

编辑2:我将发布我的通用框架脚本

对我来说只是重新启动 Xcode 解决了它。

同样在这里，某些东西似乎在后台更新了，当我启动 xcode 时，它要求安装新组件，说是的，一切又恢复正常了。 (2认同)

在我的案例中解决问题的是清除环境.显然,在Xcode中运行脚本构建阶段时,会设置一些环境变量,这些变量可能会影响Swift标准库的解析.从Xcode"Run Script"阶段执行carthage构建时遇到了这个问题.

通过以下方式清除环境来执行命令:

env -i <command>

您可能希望保留PATH和DEVELOPER_DIR环境变量,特别是当您安装了多个Xcode版本时.

所以在你的情况下

env -i DEVELOPER_DIR="$DEVELOPER_DIR" PATH="$PATH" xcodebuild ...

从[引用的迦太基GitHub问题]（https://github.com/Carthage/Carthage/issues/2613#issuecomment-471575964）来看，有问题的env变量似乎是“ LLVM_TARGET_TRIPLE_SUFFIX”。取消设置可以为我解决问题（谢谢@DávidPásztor！）。 (3认同)
