I am completely new to Python, so in order to do some practice and whatnot decided to create a venv, when I found out those exist, and do it all there.
I'm on macOS X so I already have Python2 but obviously went to get 3.
I installed the latest Python version with its package from python.org itself. Tried to get pip and venv but wouldn't work. So, then I installed Homebrew and also run the code to install python3 as well because I read it would come with pip already among other things.
It didn't come with pip and it proved terribly difficult to install it. Also creating a venv has gotten me lost since I never coded in Python before.
I've gotten everything I've done in the Terminal
I installed the latest Python3.7.3 for Mac OS X from https://www.python.org/downloads/ I ran the package and it would also supposedly come with everything but when I ran
MacBook-Air:~ maria$ pip --version
-bash: pip: command not found
So I did what their guide to install pip said
MacBook-Air:~ maria$ python -m ensurepip --default-pip
Ignoring indexes: https://pypi.python.org/simple
Requirement already satisfied (use --upgrade to upgrade): setuptools in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

Then I even installed command line developer tools from Xcode to have it all ready and make sure I'm not missing anything. After this, I installed Homebrew and used it to install python3 and I noticed it said
Error: The `brew link` step did not complete successfully

already exists. You may want to remove it:
rm '/usr/local/bin/2to3'
To force the link and overwrite all conflicting files:
brew link --overwrite python

brew link --overwrite --dry-run python

==> Caveats
Python has been installed as
/usr/local/bin/python3
So after it, I still ran
MacBook-Air:~ maria$ pip --version
-bash: pip: command not found
MacBook-Air:~ maria$ python -m ensurepip --default-pip
With the result
OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'
plus one last time
MacBook-Air:~ maria$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
but again got
Installing collected packages: pip, wheel
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip'
Consider using the `--user` option or check the permissions.
So, ended up doing the deprecated sudo easy_install pip
MacBook-Air:~ maria$ pip --version
pip 19.0.3 from /Library/Python/2.7/site-packages/pip-19.0.3-py2.7.egg/pip (python 2.7)
MacBook-Air:~ maria$ python3 -m ensurepip --default-pip

against all my fears of messing something up but that worked, ironically. The problem is I can't do venvs because I get the [Errno 13] Permission denied and I'm not sure I want to keep on experimenting and mess it up for real.
Lastly did pip install --user pipenv which said to have be worked successfully with some notes.

And I'm not sure how to proceed from here. If I installed everything correctly, if I can start now or do I need to undo something, etc. I tried the most I could possibly do before nagging anyone. I'm willing to uninstall everything and do it again from 0.
