I tried the above settings in the BUILD file, but the following error was observed.

I created and added source code that will be reproduced in the repository. #

https://github.com/peachanG/pants-sample/tree/de3279823175b5cdc9d9f9276b3a387996afa182 Sorry, I couldn’t reproduce it. How can I solve this problem?

/usr/bin/env: 'python3.6': No such file or directory

If it has to build native code from an sdist, then, just like pip, poetry and any other tool, it can only do that for the local platform.

Let me look at your specific errors and see what's going on

Ah, thanks for the reproduction repository, that is super helpful!

@bland-father-19717 since Slack is ephemeral, do you mind opening an issue for this at https://github.com/pantsbuild/pants/issues/new/choose ? Then we can track the solution properly, and make it available in the long-term for other users. Thanks!

If you read the --dest argument, that implies the resolve is happening for the local pyenv Python 3.6.8 interpreter. That in turn suggests maybe "current" is being (over?) interpreted by Pants or Pex and a resolve for the local Mac is being attempted in addition to the Linux platform resolve. It's the Mac resolve that is failing.

If you switch from "current" to the platform that matches the Macs in your dev fleet (and matches numpy available wheels), things should work.

@enough-analyst-54434 I commented on the issue, but let me thank you here as well. Thanks for the help ! I’ll close the issue.
