Folks, had a problem bootstrapping pants 5.0 for a new user. We've had no trouble, but with pants 2.5.0 and python 3.9 on a new system, this happened, as if pip wasn't seeing the right version of python:
Copy code
$ ./pants test algorithms::

...myself and our DevOps lead could not duplicate with python 3.9.5 and 3.9.2 installed. Any idea what's happening here?

Howdy, the aforementioned DevOps lead here 👋 MacOS Intel. I'm running 11.4 and the user is running 10.14.6.

there's a fourth option, build Pants from their machine and run via that wheel: https://www.pantsbuild.org/docs/installation#building-pants-from-sources

Awesome! Let us know if there's anything else we can help with or feedback 🙂 we're definitely eager to know ways we can make Pants more enjoyable to use

For sure, and thank you for the warm welcome. I do have one more question. Where is the best place to follow for such updates?

Updates like what macOS version is required? The mailing list: https://www.pantsbuild.org/docs/getting-help#mailing-list. We announce all releases and big changes like that there. (Also cross-posted to Slack. See #announce channel). But all but the most special of circumstances like this macOS change, we follow the deprecation policy at https://www.pantsbuild.org/docs/deprecation-policy. See https://www.pantsbuild.org/docs/upgrade-tips for upgrade tips And then finally https://blog.pantsbuild.org has fun project updates , usually new features 🙂

Could this not be detected by the bootstrap script, printing a nice error message. Would be a lot more helpful.. ;)
