Version: 2.18 (deprecated)


Python setuptools, used to package python_distribution targets.

Backend: pants.backend.python

Config section: [setuptools]

Basic options


Advanced options


install_from_resolve = <str>
default: None

If specified, install the tool using the lockfile for this named resolve.

This resolve must be defined in [python].resolves, as described in

The resolve's entire lockfile will be installed, unless specific requirements are listed via the requirements option, in which case only those requirements will be installed. This is useful if you don't want to invalidate the tool's outputs when the resolve incurs changes to unrelated requirements.

If unspecified, and the lockfile option is unset, the tool will be installed using the default lockfile shipped with Pants.

If unspecified, and the lockfile option is set, the tool will use the custom setuptools "tool lockfile" generated from the version and extra_requirements options. But note that this mechanism is deprecated.


--setuptools-requirements="['<str>', '<str>', ...]"
requirements = [
default: []

If install_from_resolve is specified, install these requirements, at the versions provided by the specified resolve's lockfile.

Values can be pip-style requirements (e.g., tool or tool==1.2.3 or tool>=1.2.3), or addresses of python_requirement targets (or targets that generate or depend on python_requirement targets).

The lockfile will be validated against the requirements - if a lockfile doesn't provide the requirement (at a suitable version, if the requirement specifies version constraints) Pants will error.

If unspecified, install the entire lockfile.
