Creating a Project

Virtual Environement

You can create projects with a package.json alike way, with venv.

When using Virtual Environments, dependencies installed via pip will be installed at a project scope, instead of globally.

Create the environment

python -m venv <.somename-env>

# Usually
python -m venv .venv

Active the environment

# In Windows
.\<.somename-env>\Scripts\activate
.\<.somename-env>\bin\activate

# In Linux
source <.somename-env>/bin/activate

Deactivate

deactivate

Create requirements.txt

This file will act like a package.json, saving the dependencies.

pip freeze > requirements.txt

To reinstall from a requirements.txt

Will have to recreate the environment first.

pip install -r requirements.txt
