mypy_mypyc-wheels

Automated building and storage of mypyc-compiled mypy binaries

Things to know

Typically, you'll want to report issues on the main mypy repo (not many people watch this repo)

If you're running into weird issues with a pull request, try updating the mypy_commit file to the latest hash from the mypy repo.

If wheels aren't getting built, debug over at https://github.com/mypyc/mypy_mypyc-wheels/actions

You can use pip to install these wheels like so:

pip install --upgrade --find-links https://github.com/mypyc/mypy_mypyc-wheels/releases/ mypy
# If you need a specific version, specify the url as follows
pip install --upgrade --find-links https://github.com/mypyc/mypy_mypyc-wheels/releases/expanded_assets/v0.990+dev.4ccfca162184ddbc9139f7a3abd72ce7139a2ec3 mypy

The above options may not work (and have broken in the past) since they depend on Github's HTML and pip doing the correct thing. If you're looking for a relatively bulletproof solution, navigate to the appropriate release page, manually select the wheel you wish to install and copy the URL of the correct wheel:

pip install https://github.com/mypyc/mypy_mypyc-wheels/releases/download/v0.990%2Bdev.4ccfca162184ddbc9139f7a3abd72ce7139a2ec3/mypy-0.990+dev.4ccfca162184ddbc9139f7a3abd72ce7139a2ec3-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl

Building locally

With pipx installed, run:

git clone https://github.com/python/mypy.git --recurse-submodules
git -C mypy checkout $(cat mypy_commit)
pipx run cibuildwheel --config=cibuildwheel.toml mypy

Either add --only=<identifier> to build only one wheel, or set CIBW_BUILD to some expression like cp311-* and include --platform linux (or some other platform). Optionally pin cibuildwheel to the version specified in .github/workflows/build.yml.
