1.poc_2015_0079.py:No module named objc...
why objc? if I'm running on linux instead of os x?

2.pip install pyobjc
ValueError: invalid literal for int() with base 10: ''

raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['/usr/bin/xcodebuild', '-version', '-sdk', 'macosx', 'Path']' returned non-zero exit status 1

可能需要安装依赖 XCode ？
