#18683 /usr/bin/env: <python-version> No such file or directory when using adhoc_tool runnable is pex_binary Issue created by cburroughs Describe the bug

python_source(
    name='lib-hello',
    source='hello.py')

pex_binary(
    name="hi",
    entry_point="hello.py",
)

adhoc_tool(
    name="local-data",
    runnable=":hi",
    args=["--foo"],
    output_directories=["data"],
    log_output=True,
)

python_source(
    name='lib-world',
    source='world.py',
    dependencies=[':local-data']
)

Results in

$ pants --keep-sandboxes=on_failure run hello_pex/world.py 
17:07:27.22 [INFO] Preserving local process execution dir /tmp/pants-sandbox-LcNOLX for Running the `adhoc_tool` at hello_pex:local-data

Confusingly, the

__run.sh

from the sandbox runs without error when invoked directly. so I'm not sure what is going on here. Pants version 2.16.0a0, 2.16.0rc0 OS Linux Additional info https://github.com/cburroughs/example-adhoc/tree/ad-hoc-pex pantsbuild/pants
