Install whatever Python3 package you want for your OS, along with pip. For example for Ubuntu:
$ sudo apt update $ sudo apt install python3.7 python3-pip
Go into a directory you want to use as a base and run the following:
$ python3.7 -m venv venv $ source ./venv/bin/activate $ pip install -U pip setuptools wheel
The last line is important to avoid compatibility problems when installing new packages with pip.
I work as a freelancer, so if you don’t want to do that kind of things yourself or don’t have the time, just drop me a line to hire me.
