Nothing happens when running build.py

[ruslaniv]

So I have the following:

1. Downloaded the code
2. Installed python - First problem
3. Created virtual environment and activated it
4. Installed dependencies
5. Ran ./build.pyu - Second problem

First problem:

pip file specifies

[requires]
python_version = "3.8"

Github page

The official build currently runs on Python 3.7

So which one is it?

Second problem

Absolute nothing happens when running ./build.py, powersehll immediately displays the prompt

How do I build the exe?
