Standard Py3 env on Ubuntu 20.04

If you are on Windows, use WSL2 to run this stuff.

One time preparation

Install Python3

sudo apt-get update
sudo apt-get install python3 python3-pip

Install virtualenvwrapper

pip3 install --user virtualenvwrapper
echo 'export PATH=$HOME/.local/bin:$PATH' >>~/.profile
echo 'export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3' >>~/.profile
echo 'source $HOME/.local/bin/virtualenvwrapper.sh' >>~/.profile
source ~/.profile

Install Poetry

The "vendored" version is recommended by Poetry itself.

curl -sSL https://install.python-poetry.org | python3 -

Install other tools

These are good to have available globally under your user

pip3 install --user git-up pre-commit cookiecutter

Setup SSH keys

See SSH tips & tricks document.

For each project

Here we assume the project name is "mycoolapp"

Create project virtualenv

mkvirtualenv mycoolapp

The environment will be created and activated, to activate it again later (or in another shell window) just use

workon mycoolapp

Use Cookiecutter to create the project

See the template you are going to use for details.

Setup PyCharm to use the correct env

If on native Linux (or running PyCharm under WSL) then you should be able to just choose from the existing virtualenvs. If the list is not up-to-date the correct path can be seen with command:

which python3

When the virtualenv is activated.

On Windows TBD
