chore(python-sdk): migrate from Poetry to uv by mishushakov · Pull Request #1513 · e2b-dev/E2B

mishushakov · 2026-06-30T11:55:54Z

Migrates the Python SDK's packaging and CI from Poetry to uv: pyproject.toml is converted to PEP 621 metadata using uv's native uv_build backend (verified to produce a byte-equivalent wheel containing both e2b and e2b_connect), poetry.lock is replaced with uv.lock, and the Makefile, package.json scripts, .tool-versions, CLAUDE.md, and all six GitHub workflows now use uv (astral-sh/setup-uv + uv sync/build/version/publish). It also drops the now-redundant explicit sync steps (since uv run auto-syncs) and removes the orphaned pydoc-markdown dev dependency, whose only consumer was deleted long ago — trimming 58 packages from the dev lockfile.

Usage

cd packages/python-sdk
uv sync          # install deps (replaces `poetry install`)
uv run pytest    # run tests
uv build         # build the wheel/sdist
make lint        # ruff (run via `uv run`)

No user-facing SDK change — packaging/tooling only — so no changeset is included; the published package contents are unchanged.

Switch the Python SDK's packaging and CI tooling from Poetry to uv: convert pyproject.toml to PEP 621 metadata with the native uv_build backend, replace poetry.lock with uv.lock, and update the Makefile, package.json scripts, .tool-versions, and all GitHub workflows to use uv. Also drop the redundant sync steps (uv run auto-syncs) and the orphaned pydoc-markdown dev dependency. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

PR Summary

Medium Risk
Changes PyPI publish and CI install/build paths for the Python SDK; runtime library code is untouched, but a misconfigured uv publish or lockfile drift could break releases or CI.

Overview
Migrates Python SDK packaging and tooling from Poetry to uv with no intended change to the published e2b package contents.

pyproject.toml is rewritten as PEP 621 metadata with uv_build (still shipping e2b and e2b_connect), poetry.lock is removed in favor of uv.lock, and dev deps move to [dependency-groups]. pydoc-markdown is dropped from dev deps; codegen tools live in a separate codegen group used by make init (uv sync --group codegen).

CI and local scripts swap setup-python + snok/install-poetry for astral-sh/setup-uv@v6 (pinned via .tool-versions: uv 0.10.0 replaces poetry). Workflows use uv sync --locked, uv build, uv version, and uv publish --token … --check-url … instead of Poetry equivalents. package.json and the Makefile route test/lint/publish through uv run; the standalone setup target is removed.

CLAUDE.md now tells contributors to use uv for Python dependencies.

JS SDK (e2b@2.31.1-mishushakov-python-poetry-to-uv.0):

npm install ./e2b-2.31.1-mishushakov-python-poetry-to-uv.0.tgz

CLI (@e2b/cli@2.13.1-mishushakov-python-poetry-to-uv.0):

npm install ./e2b-cli-2.13.1-mishushakov-python-poetry-to-uv.0.tgz

Python SDK (e2b==2.30.0+mishushakov.python.poetry.to.uv):

pip install ./e2b-2.30.0+mishushakov.python.poetry.to.uv-py3-none-any.whl

The init target pip-installed codegen tools, but it was unreferenced, inconsistent with codegen.Dockerfile (which uses the patched e2b-openapi-python-client fork), and datamodel-code-generator is now a dev dependency installed by `uv sync`.

uv appends the package name to --check-url, so the project page (.../simple/e2b/) gave the wrong prefix for duplicate-file detection. Use the simple index root (.../simple/) so skip-existing works on publish and RC workflows. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Bare `uv sync` silently re-resolves and rewrites uv.lock when pyproject.toml drifts, unlike Poetry's non-mutating install. --locked mirrors `pnpm install --frozen-lockfile` so CI fails with the real cause instead of the misleading lint formatting error. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

uv provisions and pins the interpreter through setup-uv's python-version input (fed from .tool-versions), so all uv commands use it. No workflow invokes python directly, so the separate setup-python step is redundant. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Local code generation needs pyyaml (for remove_extra_tags.py) and the patched e2b-openapi-python-client, which were only ever available inside the codegen Docker image. Add a pinned `codegen` dependency group (mirroring codegen.Dockerfile) and restore `make init` as `uv sync --group codegen` so `uv run make generate-api` works locally. datamodel-code-generator moves from dev into codegen since it is only a generation tool. generate-envd still needs Docker (Go/buf).
