Poetry¶
Python packaging and dependency management made easy.
# Install solution and dependencies
$ poetry install
# Install dependencies only
$ poetry install --no-root
# Add depencency
$ poetry add pendulum
# Update dependencies to latest versions
$ poetry update
# Run cmd in poetry virtual environment
$ poetry run python your_script.py
$ poetry run pytest
Notes:¶
Poetry will try to find a common version of a dependency across all specified Python versions.
EX: we put python=”*” in pyproject.py and it installed a very old version, presumably 2.7 compliant, of a depencency that wouldn’t work with our installed environment.
Edit pyproject.toml to enable pip install -e .
