无法为 python 3.8.0 安装 pyobjc-core MacO（命令“gcc”失败，退出状态为 1）

Question

OS: macOS Big Sur: 11.0.1 Python: 3.8.0

trying to install pyobjc-core==5.2 to fulfill the requirements for the "automate the boring stuff" book.

I have tried many suggested fixes online and have yet to find a solution in this particular case. Was able to get this all installed on my windows machine but I am not familiar with macOS.

Here is the output:

    Running setup.py install for pyobjc-core ... error

Alright I installed brew and then using brew installed zlib and libpng, the resulting error is a CalledProcessError after attempting to install pyobjc-core again.

Answer 1

Welp, im assuming that newer versions of pyobjc/core/frameworkQuartz will work similarly when it comes to following along the book ive been reading. so I went ahead and stopped trying to install those particular versions mentioned in said book.

Had no more issues after I installed the newest version being 7.0.1
