Python 3.7.4 isn't being used

Question

I'm trying to install BEE2, and the only problem I'm running into is that it's using Python 2.7.15+, but needs Python 3.6+. I'm on Ubuntu 18.04.03.

I run python -v, and it tells me that 2.7.15 is the latest version. python3 -v tells me I have Python 3.7.4 installed though. While running apt install, I get the same results. Both are at the latest version.

Do I need to force pyinstaller to use Python 3?

So, python will never be Python 3. Any app that requires python3 should have #!/usr/bin/env python3 or similar at the top of the script, or you should run it with python3 app. I don't know how you're installing BEE2, but it probably needs to be done so with whatever script uses python3 instead of 2. — dobey, Aug 16 '19 at 19:20
I'm going by the install directions on the repository in the README.

You can use update-alternatives to set the default python version. I have provided instructions on how to do that in my answer below. — Gordster, Aug 16 '19 at 23:19

I have taken my own answer from a similar question found here

Switching between python versions using update-alternatives:

If setting up virtual environments is not what you want to do, then you can also use update-alternatives to switch between python version. Run these two commands first, but make sure the python versions match what you have on your computer

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1 sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 2

You may then run update-alternatives with the --config option so that you may select which version you want to choose to be the default

$ sudo update-alternatives --config python

Use the interactive menu to select which version you would like to use as the default. In order to check if your changes have worked you can use python --version

adding from comments: you may have to install python-pip3 if pip no longer works after changing the default python version. install it by running sudo apt install python3-pip

PyInstaller isn't working anymore, and PIP isn't recognized. – CStafford-14 Aug 17 '19 at 00:17
Should I reboot? – CStafford-14 Aug 17 '19 at 00:24
You may have to install pip3 sudo apt-get install python3-pip. After Doing that you can try your installations again. On this page they recommend trying python -m pip install *package* but if that's not applicable for pyinstaller then I apologize – Gordster Aug 17 '19 at 00:40

That was the problem. Now, I've gotten further and am now stuck with a BEEMod issue. Thanks! – CStafford-14 Aug 17 '19 at 00:53
Is it python3-pip or python-pip3? – CStafford-14 Aug 19 '19 at 14:10
python3-pip. Thank you for clarifying @CStafford-14 – Gordster Aug 19 '19 at 18:10
