pipenv-poetry-migrate

This is simple migration script, migrate pipenv to poetry.

:rocket: Get Started

Installation

$ pip install -U poetry pipenv-poetry-migrate

Migration

Step 1: Create pyproject.toml file

$ poetry init

Step 2: Migrate

To migrate Pipfile to pyproject.toml.

$ pipenv-poetry-migrate -f Pipfile -t pyproject.toml

When want to run dry-run mode:

$ pipenv-poetry-migrate -f Pipfile -t pyproject.toml -n

Dry-run mode is pyproject.toml file does not overwrite, results are displayed on standard output.

Note
If the dependency already exists in the poetry dependency and you want to re-migrate it, please use the --re-migrate option. However, if the dependency is removed from pipenv, the poetry dependency is not removed.

$ pipenv-poetry-migrate -f Pipfile -t pyproject.toml --re-migrate

Note
The default behavior is to migrate with the group notation, which has been available since Poetry 1.2.0. If you want to migrate with dev-dependencies notation, please use the --on-use-group-notation option.

$ pipenv-poetry-migrate -f Pipfile -t pyproject.toml --no-use-group-notation

Step 3: Generate lock file

$ poetry lock

If there is already a poetry.lock file, remove it first.

Step 4: Installing dependencies

To install the defined dependencies for your project.

$ poetry install

Example output

This is an example of a Pipfile to be migrated.

[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages]
requests = "*"

[dev-packages]
pytest = "^5.2"

Migrate the above file to the following pyproject.toml.

[tool.poetry]
name = "migration-sample"
version = "0.1.0"
description = ""
authors = ["Yoshiyuki HINO <yhinoz@gmail.com>"]

[tool.poetry.dependencies]
python = "^3.7"

[tool.poetry.group.dev.dependencies]

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

By executing this script, pyproject.toml is rewritten as follows.

[tool.poetry]
name = "migration-sample"
version = "0.1.0"
description = ""
authors = ["Yoshiyuki HINO <yhinoz@gmail.com>"]

[tool.poetry.dependencies]
python = "^3.7"
requests = "*"

[tool.poetry.group.dev.dependencies]
pytest = "^5.2"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"
