Way too many errors when building wheels on Mac

[Meroniice]

Before I got to this stage, it's been very easy to find out what dependencies I've been missing and using pip to install them as the error codes were relatively small and only had a few lines of output. However, this error that I've gotten for the process of building wheels for opency-python and Pillow-SIMD on the requirements.txt file is overwhelming to me. Anyone knows a solution to this or someone that has completed the installation for Mac? All help is appreciated.

Here's the output, omitting the identification for my MacOS 10.14.6 terminal:

And here's the text file I copied from if the Pastebin link doesn't work.
