09/15/2023, 5:14 PMI think the best way is to do precisely what was described in the previous thread, that is have
pexpex_binarycurved-television-6568
09/15/2023, 5:16 PMhmm… maybe there’s a tool resolve you could tap into, so you could skip the requirement part.. 🤔

09/15/2023, 5:16 PM@brief-flag-35586 what @curved-television-6568 says is true, but that won't match the Pex version Pants uses. What are you trying to do exactly in more detail?

09/15/2023, 5:19 PMI’m trying to export dependencies into some kind of lock file.
We have a pants generated lock file
default.lock Copy code
pants pex-cli -- lock export default.lock > requiremenets.locke

09/15/2023, 5:20 PMI'd personally just not use Pants there. That's an extra layer for no real purpose.

09/15/2023, 5:22 PMSo, @brief-flag-35586 you need a hashed requirements.txt ~lock for some other tool to use?

09/15/2023, 5:23 PMI just thought that as pants already have pex integrated, there should be a way to use it, but looks like my assumption wasn’t correct

09/15/2023, 5:24 PMThat's right. Your assumption was incorrect. There is no easy way to use Pants's Pex directly.

09/15/2023, 5:25 PMIn your favor though is, unlike Pants, Pex never breaks you. It's always backwards compatible. So you should be able to use ~any version of Pex and have it work with your Pants generated lock file.

09/15/2023, 5:26 PMn.b. that pants adds a comment header to the lockfile that needs to be stripped before being handed to pex.

09/15/2023, 5:26 PMAh, yes. See, Pants breaks you! That really, really is unfortunate.
