Limiting versions of python used while building a formula

Description of issue

Various formulae have build dependencies on multiple versions of python (e.g., , cryptography depends on python@3.11, python@3.12, and python@3.13).

When installing/upgrading, can I limit the build / build dependencies to just one of them?

If so, must I manually specify what python versions to use/skip? Or can I just say: only build for the python versions that are currently installed?

All of my installed python formulae have python@3.12 as their runtime dependency.

At the least, I'd prefer to be able to ignore 3.11 (i.e. not install 3.11 for build, and not output 3.11 versions of the formulae), because I presumably will never use 3.11 again.

No, this is not possible. Builds will only every build what is defined in the formula, there is no method to modify this.

[rgoldberg]

Thanks for the info. Do you think it would be difficult to add in a flag to brew install that makes it ignore certain dependencies & to add support in formulae to ignore a block if a dependency was ignored? Presumably, this info would have to be remembered for subsequent brew upgrades to follow suit.

You can create your own tap and do whatever you want, but we wouldn't support something like this.
