Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 bsddb185
dbm dl imageop
linuxaudiodev nis ossaudiodev
spwd sunaudiodev zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
Failed to build these modules:
_Qt _tkinter
running build_scripts
running install_lib
这是由于 CTL 把一些头文件移动了位置，需要单独额外按照，方式如下：
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
