Sure thing. To help me test this, how can I reproduce this failure? I just ran

pip install blake3 --no-binary=blake3

and also

pip install blake3 --no-binary=:all:

in clean virtualenvs, and both seem to succeed (on currrent Arch Linux).

Sure, the build is failing on macOS 11 with Python 3.10 and version 1.55 of the rust toolchain + cargo

$ cargo build
    Updating crates.io index
error: failed to select a version for the requirement `pyo3 = "^0.14"`
candidate versions found which didn't match: 0.13.2, 0.13.1, 0.13.0, ...
location searched: crates.io index
required by package `blake3 v0.2.0 (/Users/robd/code/blake3-py)`

[robd003]

Turns out it was an issue with the homebrew version of rust. I'm submitting a patch and macOS users should be fine after that.

Good to know. In any case we did just cut a new release, v0.2.1.
