MacOS工程cmdline运行失败

Hello,

当我按照你们Mac环境的wiki，compile_mac.md依次执行下面的命令：
. setup.env
cd external/
./build_external.sh macOS
,当执行到最后一个命令./build_external.sh macOS，报如下错误，请问这个应该如何解决？


Start with compile_mac.md and reproduce the sequence using . setup.env, cd external/, and ./build_external.sh macOS. Inspect the error shown in the issue screenshot and the external build script to identify the failing step. Done means the external dependencies build successfully on macOS using the documented commands.
