Customization

This document covers advanced customization options including checksum validation, custom manifests, and problem matchers.

Validate checksum

You can specify a checksum to validate the downloaded executable. Checksums up to the default version are automatically verified by this action. The sha256 hashes can be found on the releases page of the uv repo.

- name: Install a specific version and validate the checksum
  uses: astral-sh/setup-uv@v7
  with:
    version: "0.3.1"
    checksum: "e11b01402ab645392c7ad6044db63d37e4fd1e745e015306993b07695ea5f9f8"

Manifest file

By default, setup-uv reads version metadata from astral-sh/versions (NDJSON format).

The manifest-file input lets you override that source with your own URL, for example to test custom uv builds or alternate download locations.

Format

The manifest file must be in NDJSON format, where each line is a JSON object representing a version and its artifacts. For example:

{"version":"0.10.7","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
{"version":"0.10.6","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}

setup-uv currently only supports default as the variant.

The archive_format field is currently ignored.

Legacy format: JSON array (deprecated)

The previous JSON array format is still supported for compatibility, but deprecated and will be removed in a future major release.

[
  {
    "version": "0.7.13",
    "artifactName": "uv-aarch64-apple-darwin.tar.gz",
    "arch": "aarch64",
    "platform": "apple-darwin",
    "downloadUrl": "https://github.com/astral-sh/uv/releases/download/0.7.13/uv-aarch64-apple-darwin.tar.gz"
  }
]

- name: Use a custom manifest file
  uses: astral-sh/setup-uv@v7
  with:
    manifest-file: "https://example.com/my-custom-manifest.ndjson"

Note

When you use a custom manifest file and do not set the version input, setup-uv installs the latest version from that custom manifest.

Add problem matchers

This action automatically adds problem matchers for python errors.

You can disable this by setting the add-problem-matchers input to false.

- name: Install the latest version of uv without problem matchers
  uses: astral-sh/setup-uv@v7
  with:
    add-problem-matchers: false
