Poetry

• It is a new Python Package manager.
• It combines Virtualenv and pip.
• It can create python virtual environment.
• It can manage python project dependencies.
• It is faster than pipenv and more reliable tool than pipenv.

Installation:

• sudo apt install curl
• curl -sSL https://install.python-poetry.org | python3 – Open bashrc file (vim ~/.bashrc) and add export PATH = $PATH:$HOME/.local/bin

Virtual environment is a copy of your python installation. Any python package manager install all packages for that particular python installation. It’s better to set up a directory where poetry set up python and its packages.

• poetry –v
• poetry config –list

To change the directory where poetry stores virtual environment ~/.cache/pypoetry/virtualenvs run the command

• poetry config virtualenvs.in-project true
• poetry init
• poetry init –n

It will create a file pyproject.toml which will carry all dependencies (Production and Execution)

• poetry new new_project
• poetry add django (Automatically created and generated a virtual environment for project and istall all te dependencies)

Example:

Create new file main.py for project and write:

from django import VERSION

print (Version)

---

• python main.py (Error: Unknown django )
• poetry run python main.py (No Error since poetry added all dependencies)
• poetry shell
• python main.py
• python –i main.py
• poetry show –tree
• poetry remove django
