1.6.0 has no intel macos wheels

[Christos-Hadjinikolis]

Hello,

I encountered an issue when attempting to install libcst==1.6.0 using Python 3.10. The installation fails with the following error message:

error: can't find Rust compiler

If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

To update pip, run:

    pip install --upgrade pip

and then retry package installation.

If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

This appears to be related to the upgrade of PyO3 to version 0.22 in PR #1180. It seems that the dependency on a Rust compiler was introduced with this change.

This issue makes it impossible to install libcst without a Rust compiler, which could be problematic for environments that do not have Rust installed.

Could you please clarify whether this behavior is intended? If not, is there a plan to provide prebuilt wheels for libcst==1.6.0 that would not require a Rust compiler?

Thank you!

libcst has had a dependency on rust since 0.4.0 a couple of years ago, and there are prebuilt wheels provided accordingly as you can check for yourself at https://pypi.org/project/libcst/#files

Are you by any chance running on an intel mac?

[Christos-Hadjinikolis]

Yes (running on Intel MacOs). And installing 1.5.1 was fine.

OK so that's going to be because #1275
I'm happy to accept a PR that restores intel wheels if someone can resolve the issue
