How Pants uses Pex to run Python subprocesses.

Backend: pants.core
Config section: [pex]

Basic options

None

Advanced options

`executable_search_paths`

--pex-executable-search-paths="[<binary-paths>, <binary-paths>, ...]"

PANTS_PEX_EXECUTABLE_SEARCH_PATHS

default:

[
  "<PATH>"
]

The PATH value that will be used by the PEX subprocess and any subprocesses it spawns.

The special string "<PATH>" will expand to the contents of the PATH env var.

`verbosity`

--pex-verbosity=<int>

PANTS_PEX_VERBOSITY

default: 0

Set the verbosity level of PEX logging, from 0 (no logging) up to 9 (max logging).

`venv_use_symlinks`

--[no-]pex-venv-use-symlinks

PANTS_PEX_VENV_USE_SYMLINKS

default: False

When possible, use venvs whose site-packages directories are populated with symlinks.

Enabling this can save space in the --named-caches-dir directory and lead to slightly faster execution times for Pants Python goals. Some distributions do not work with symlinked venvs though, so you may not be able to enable this optimization as a result.

Deprecated options

None
