Error Installing Matplotlib on Python 3.8
RESOLVED: Installing Xcode on my Mac installed all missing dependencies of Matplotlib, thus I was able to successfully install Matplotlib via Terminal.
I currently have Python 2.7 and Python 3.8 (downloaded the .dmg via Python.org) on my Mac OS X Catalina. I have successfully installed Numpy via Terminal, as well as Matplotlib on Python 2.7 via Terminal, but I always get two error codes when I install Matplotlib through Terminal. I've tried using different variants of inputs via terminal via troubleshooting I did in my online research, but to no avail.
Input:
pip3 install matplotlib
Output (Error #1):
