具体报错如下：
have the same architectures (arm64) and can't be in the same fat output file
1、把以下内容写入文件 /tmp/helper.xcconfig
EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64=arm64 arm64e armv7 armv7s armv6 armv8
EXCLUDED_ARCHS=$(inherited) $(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT))
2、执行：
export XCODE_XCCONFIG_FILE=/tmp/helper.xcconfig
3、然后编译：
carthage build --platform iOS --no-use-binaries --cache-builds
