如何在运行时用系统python/pyobjc修复MacOSX10.15上的AVFoundation桥支持？

import os
import subprocess
import sys

def fix_avfoundation_bridge():
    try:
        subprocess.check_output(['xcode-select', '--install'], stderr=subprocess.STDOUT)
        subprocess.check_output(['sudo', 'xcode-select', '--reset'], stderr=subprocess.STDOUT)
        subprocess.check_output(['sudo', 'xcodebuild', '-license'], stderr=subprocess.STDOUT)
        subprocess.check_output(['sudo', 'xcode-select', '--switch', '/Library/Developer/CommandLineTools'], stderr=subprocess.STDOUT)
        subprocess.check_output(['sudo', 'installer', '-pkg', '/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg', '-target', '/'], stderr=subprocess.STDOUT)
        subprocess.check_output(['sudo', 'ln', '-sf', '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/AVFoundation.framework/Versions/A/AVFoundation', '/System/Library/Frameworks/AVFoundation.framework/Versions/A/AVFoundation'])
    except Exception as e:
        print("修复AVFoundation桥支持时出错：" + str(e))
        sys.exit(1)

if __name__ == '__main__':
    fix_avfoundation_bridge()
    print("AVFoundation桥支持修复成功！")
    sys.exit(0)

python fix_avfoundation_bridge.py
