BinaryNotFoundError when trying to pack pex

[allcupsnotinprivate]

I have a monorepo managed by pants. The build files and application structure are the same for all services in it. But out of all the services, only one does not start: files_service. When calling pants run the files_service starts successfully, but when calling pants package for files_service-bin the following error occurs:

Engine traceback:
  in `package` goal

BinaryNotFoundError: Cannot find `unzip` on `['/bin', '/opt/homebrew/bin', '/usr/bin', '/usr/local/bin']`. Please ensure that it is installed so that Pants can download the tools Pants needs to run.

In addition, it is the only service that implements proto interfaces as a server. All proto are defined in folder with BUILD file through the target in it:

protobuf_sources(
    name="protos",
    sources=[
        "files/v1/chat.proto",
        "files/v1/backups.proto",
    ],
    grpc=True,
)

System info:

~ % sw_vers

ProductVersion:		14.0
BuildVersion:		23A344

There is unzip in the environment. The path to it:

~ % which unzip
/usr/bin/unzip

The problem was solved when building under certain conditions (in Linux). To do this, I defined the working and target environments in the root build, then used them when running.

local_environment(
    name="macos",
    compatible_platforms=["macos_arm64"]
)

local_environment(
    name="linux",
    compatible_platforms=["linux_x86_64"],
    fallback_environment="docker"
)

docker_environment(
  name="docker",
  platform="linux_x86_64",
  image="python:3.12",
)

Glad you found a solution!
