Introduction

Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

System requirements

Poetry requires Python 2.7 or 3.4+. It is multi-platform and the goal is to make it work equally well on Windows, Linux and OSX.

Installation

Poetry provides a custom installer that will install poetry isolated from the rest of your system by vendorizing its dependencies. This is the recommended way of installing poetry.

curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python

Alternatively, you can download the get-poetry.py file and execute it separately.

If you want to install prerelease versions, you can do so by passing --preview to get-poetry.py:

python get-poetry.py --preview

Similarly, if you want to install a specific version, you can use --version:

python get-poetry.py --version 0.7.0

Note

Using pip to install poetry is also possible.

pip install --user poetry

Be aware, however, that it will also install poetry's dependencies which might cause conflicts.

Updating poetry

Updating poetry to the latest stable version is as simple as calling the self:update command.

poetry self:update

If you want to install prerelease versions, you can use the --preview option.

poetry self:update --preview

And finally, if you want to install a spcific version you can pass it as an argument to self:update.

poetry self:update 0.8.0
