Hey @enough-analyst-54434, is it possible for this error message to be enriched with Pex to say what the current platform is? I'm befuddled trying to debug a Pants test:

pantsbuild.pants-2.8.0.dev1-cp39-cp39-macosx_10_16_arm64.whl is not a supported wheel on this platform.

If so, will open up a Pex feature request

It should be. Before the feature though does upping pex verbosity reveal the answer?

Ah good idea. It does. Looks like Pants is building Py39 via

runtime_package_dependencies

for

pep561_integration_test.py

, but the test is trying to use Py38. So it fails. Thanks! I can still open the feature request, though

Its a slightly odd feature for Pex, since when you use interactively on the CLI, presumably you know what you're doing. In this Pants case there are layers so it;s much less clear. Worst case Pex interactive error messages get a bit redundant.
