#2026 Using `--complete-platform` with `--resolve-local-platforms` should build sdists when local platform provides a subset of complete-platforms Issue created by shalabhc Summary If a builder platform is capable of building sdists into wheels that are compatible with a target platform, then

pex --complete-platform=cp-generated-from-target.json --resolve-local-platforms

should build any pex on the builder, including any sdists. Example where this doesn't work • builder: PyPA official wheel builder

<http://quay.io/pypa/manylinux2014_x86_64|quay.io/pypa/manylinux2014_x86_64>

• target:

python:3.10-slim

source Steps to reproduce 1. Generate the complete-platform.json (py310-complete-platform.json.zip)

% docker run --platform=linux/amd64 -it python:3.10-slim /bin/bash -c 'pip3 install pex==2.1.119 --quiet --quiet --quiet; pex3 interpreter inspect --markers --tags;' > py310-complete-platform.json

2. Prepare the builder

% docker run --platform=linux/amd64 -it -v ${PWD}:/curdir <http://quay.io/pypa/manylinux2014_x86_64|quay.io/pypa/manylinux2014_x86_64>            
    [root@3a4bc9eae7f5 /]# export PATH=/opt/python/cp310-cp310/bin/:$PATH
    [root@3a4bc9eae7f5 /]# python3.10 --version
    Python 3.10.9
    [root@3a4bc9eae7f5 /]# which pip3
    /opt/python/cp310-cp310/bin/pip3
    [root@3a4bc9eae7f5 /]# pip3 install pex

    [root@3a4bc9eae7f5 curdir]# cd /curdir

3. Build the PEX (note there is no wheel for

pendulum

for Python 3.10)

[root@3a4bc9eae7f5 curdir]# pex --python=python3.10 --complete-platform=py310-complete-platform.json --pip-version=22.2.2 --resolver-version=pip-2020-resolver pendulum==2.1.2 -o pendulum.pex --resolve-local-platforms

    ERROR: Could not find a version that satisfies the requirement pendulum==2.1.2 (from versions: 0.3.1, 0.4, 3.0.0a1)
    ERROR: No matching distribution found for pendulum==2.1.2

Alternatives tried • using

--interpreter-constraint

instead of

--python

-> same error as above • using

--platform=manylinux2014_x86_64-cp-310-cp310

instead of

--complete-platform

• build succeeded • run succeeded - I was able to run the built pex on the target, which means this was a compatible wheel • the built wheel was

manylinux_2_17

:

unzip -l pendulum-b.pex | grep 'whl/$'
