I'm getting errors while installing pygame on my Chromebook, and to make matters worse, the website is down? Please tell me why

Question

I am trying to install pygame on my Chromebook (using the Linux 'Terminal' app included with Chrome Developer Mode) with the following command:

python3 -m pip install -U pygame --user

I found these instructions HERE: https://www.pygame.org/wiki/GettingStarted

I am constantly getting the same error:

denverhogan3@penguin:~$ python3 -m pip install -U pygame --user

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-joiz94kc/pygame/

I tried a couple of solutions to those problems but nothing worked for me (I tried upgrading pip, uninstalling python2 and some other options).

I also tried visiting the website described by the error, but it came back to being non-existant?!

I would be sincerely grateful if someone can help me with this problem and explain the situation as I am fairly new to python.

I am using:

-a Lenovo 32GB Chromebook with an ARM64 chip (found using the command $ sudo apt --version),

-python 3.7.3 64-bit (python version found using the command $ python3 --version),

-pip 18.1 (pip version found using the command $ python3 -m pip --version)

Also, I have 7.5 GB of disk space dedicated to Linux applications.

Thank you SO much!
