Hi folks ! I see a lot of discussions around docker and pex. Maybe someone can help me on the issue ? In a nutshell, when I use

docker_image

to run a pex with

platforms

specified, I get

/usr/bin/env: 'python3.9': No such file or directory

I have no idea where

3.9

comes from. I don't have it on my system, I use

3.10

everywhere in files and configurations.

I had this same problem too starting with 2.16.0. Here is a work around that worked for me. In

pants.toml

, tell pants to use your PYENV installs to run pex. It defaults to

"<PATH>"

[pex]
executable_search_paths = ["<PYENV>"]

Then, where you build your PEX targets, override the default shebang line

pex_binary(
    name="bin",
    entry_point="foo.bar.main",
    shebang="#!/usr/bin/env python3",
)

Thanks ! That worked 🙂
