Short notes about #py/poetry for package management

poetry new packagename creates a poetry project

From within the folder with the package:

• poetry install == pip3 install -r requierements.txt
• poetry shell == source .venv/bin/activate
• exit == deactivate

Basic usage | Documentation | Poetry - Python dependency management and packaging made easy:

• venvs live in {cache-dir}/virtualenvs, which on my box is /home/me/.cache/pypoetry/virtualenvs/ptest-eeSDLvcF-py3.6/bin/activate
• poetry.lock caches the resolved packages once we install things once.
  • Must mach pyproject.toml, a warning will be shown otherwise
  • It’s important to commit it to a VCS! It has the exact versions it resolves, beneficial for everyone to use them
• poetry update updates everything to the latest versions, overwriting poetry.lock
• poetry init initializes a project and creates a pyproject.toml interactively, allowing even to search for packages etc!

Adding packages:

• poetry add yaml adds a package
• poetry search yaml looks for packages in remote repos! Will tell you that you actually want pyyaml
