README.md

pyenv-binary (experimental)

Package an installed Python version into a relocatable archive that can be installed on another machine.

This is experimental and intentionally decoupled: it does not change pyenv install or any other command. You drive it explicitly through pyenv binary. Run pyenv binary <command> --help for details on a command.

Portability

An archive is portable across machines that share its build platform (OS, architecture and a compatible libc) and have the recorded system libraries. It is not portable across, say, glibc and musl, or to an older glibc; the platform and dependency metadata exist to catch that.

Commands

pyenv binary save <version> [<output-dir>]

Packs an installed version into <version>-<platform>.tar.gz (relative paths) and writes <version>-<platform>.meta describing the build platform (OS, arch, distro and libc version) and the system libraries the build links against.
