Mismatched local wheels can fail silently and be hard to debug

[codebreach]

If a local wheel is present with the wrong version there is no indication of why its not used

leaving this here as a comment in case someone in the future gets stumped by this

to make it more obvious you can replace

rules_pycross/pycross/private/tools/bzl_lock_generator.py

Lines 238 to 242 in 757033f

	# Override per-file with given local wheel labels
	for filename, local_label in self.local_wheels.items():
	name, version, _, _ = parse_wheel_filename(filename)
	if (package.name, package.version) == (name, version):
	package_sources[filename] = PackageSource(label=local_label)

with the following

            # has name_version and just name as specified in local_wheels
            # used to warn the user if a name is specified but version does not match
            specified_local_wheels = set() 
            
            # Override per-file with given local wheel labels
            for filename, local_label in self.local_wheels.items():
                name, version, _, _ = parse_wheel_filename(filename)
                specified_local_wheels.add(name)
                specified_local_wheels.add(f"{name}_{version}")
                
                if (package.name, package.version) == (name, version):
                    package_sources[filename] = PackageSource(label=local_label)

            if package.name in specified_local_wheels and f"{package.name}_{package.version}" not in specified_local_wheels:
                print(f"WARNING: {package.name} is specified in local_wheels but version does not match version {package.version} of package used in lock file.")
