Unable to generate stubs locally using uvx

[kishaningithub]

I ran the exact same command mentioned in the documentation but got the following error

$ uvx --with 'boto3==1.36.19' mypy_boto3_builder

The executable `mypy-boto3-builder` was not found.
warning: An executable named `mypy-boto3-builder` is not provided by package `mypy-boto3-builder`.
The following executables are provided by `mypy-boto3-builder`:
- mypy_boto3_builder
Consider using `uvx --from mypy-boto3-builder <EXECUTABLE_NAME>` instead.

Additional context

$ uvx --version
uv-tool-uvx 0.5.31 (Homebrew 2025-02-12)

Hello!

Thank you for the report.

EDIT: outdated, fixed in the latest release

Yes, automated daily builds also fail because of this. It must be related to new uv release https://github.com/astral-sh/uv/releases/tag/0.5.31

Downgrading uv to 0.5.30 works for me, so you can try as well: uv self update 0.5.30.

Or use the latest uv the way they recommend: uvx --with 'boto3=1.36.19' --from mypy-boto3-builder mypy_boto3_builder ...

I am going to figure out what is going on and release an update today.

Fixed in the latest release 8.9.1. Please test and let me know if it works as expected.

It looks like the latest uvx does not use package name to find main executable, but instead uses canonicalized package name: mypy_boto3_builder -> mypy-boto3-builder. So, I added a new CLI executable. Now it should be compatible with all uv versions.

Thanks for the fix ! :-)

This is the exact command which worked for me uvx --with 'boto3==1.36.19' mypy-boto3-builder

I think this issue can be closed once the documentation site is also updated

[vemel]

Yes, it makes sense to update the documentation. Will do.

[vemel]

I have just released a new version of builder. Docs should be auto updated today.
