Thanks for your reply.

I have try the master(latest) and v4.3.1 on https://docs.espressif.com/, both give me same error.

Also tried the some of the suggestions in https://stackoverflow.com/a/43855394/9309705, but still got the same

Used a Window10 machine and make it work with the hello world program.
But IDF Version 4.3.1 doesn't work for ESP32s3, need to install version 4.4.

Now, coming back to my Mac and try to install ESP32-IDF...........
