When I cargo publish from the package directory in my workspace, I get:

error: Source directory was modified by build.rs during cargo publish. Build scripts should not modify anything outside of OUT_DIR.
Added: {workspace_dir}/target/package/{package_name}-{version}/Cargo.lock

To proceed despite this, pass the `--no-verify` flag.

I’ve tried using cargo generate-lockfile from the package directory, including with the --lockfile-path, but it keeps generating a lockfile for the entire workspace. How do I generate the lockfile for just this one package?

I tried to run cargo package and commit the lock file back into the package folder, but I get the same error. I confirmed that the file is the same, by checking that diff {package_name}/Cargo.lock target/package/{package_name}-{version}/Cargo.lock is empty.

I would also accept a solution that stops generating the Cargo.lock file, since this package is a library without a binary. Although I understand that Rust is moving toward always publishing Cargo.lock, so it’s slightly less preferred.
