Pants v2: The ergonomic build system

Welcome to the Pants v2 documentation hub!

Pants v2 is a fast, scalable, user-friendly build system for growing codebases. It's currently focused on Python, with support for other languages coming soon.

Here you'll find guides to help you get started with Pants v2, comprehensive documentation on how to configure, run and customize Pants v2, and information on how to get help from the Pants community.

Get Started

How Pants uses Pex to run Python subprocesses.

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.


bootstrap_interpreter_names

--pex-bootstrap-interpreter-names="[<bootstrap-python-names>, <bootstrap-python-names>, ...]"
PANTS_PEX_BOOTSTRAP_INTERPRETER_NAMES
default:
[
  "python",
  "python3",
  "python2"
]

The names of Python binaries to search for to bootstrap PEX files with.

This does not impact which Python interpreter is used to run your code, only what is used to run the PEX tool. See the interpreter_search_paths option in [python-setup] to influence where interpreters are searched for.


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).


Deprecated options
