How to share environment, specifically files, across multiple commands

[dgilman-hrp]

Is it possible to share the file output across multiple commands?

compile_pip_requirements(
    name = "requirements",
    requirements_in = "requirements.in",
    requirements_txt = "requirements.txt",
    verbose = True,
)

py_venv(
    name = "venv",
    data = all_data_requirements,
    venv_location = "backend/code/.venv",
    deps = all_requirements,
)

multirun(
    name = "reqs",
    commands = [
        "requirements.update",
        "venv"
    ],
)

Running this command yields:

   with open(os.environ["BUILD_ENV_INPUT"]) as f:
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'bazel-out/darwin_arm64-fastbuild/bin/backend/code/_venv_deps.json'

Is there a recommended way to string these together?
