The error indicates it is not able to find the python3.9 library. It is looking in /Applications/Xocde.app/Contents/Developer/Library/Framework/Python3.framework/Versions/3.9/lib but this directory does not exist. Is that the correct directory where your python is installed? I believe it is trying to find libpython3.9.dylib, so I recommend trying to find that file and figuring out why it is not in the directory where it is expecting it. On linux we occasionally see reports from people who can find libpython because they did not build python with the --enable-shared option so if you built python from source you may need to set that option.

• I can find libpython3.9.dylib at following paths：

  /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/config-3.9-darwin/libpython3.9.dylib
  /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/libpython3.9.dylib

• python on my mac is installed by Xcode, so I did not build python
• So do I need to re_install Xcode? or other operations ? Thanks

Your screenshot shows it's looking for the Python library under XCode but you have it installed elsewhere. I'm not sure why it's looking in the wrong place. The relevant part of the build is here in commands/python.py. If you want a quick and dirty fix, you could change that to use a hardcoded path of the directory like this

return ['-L{0}'.format('/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib')]

For a more permanent fix, I recommend searching online for how to set Xcode to use a specific Python that you've installed. Maybe that would make sysconfig.get_config_var('LIBDIR') return the right directory. If you figure it out, please come back and share what you've found as I doubt you'll be the only one to encounter this.

You can use my distros as a Java dependency, https://github.com/icemachined/jep-distro. It contains arm64 binaries for all python versions with numpy integration available.
