Hi, I just upgraded to 2.10 and fix all the BUILD file errors. Now I am trying to build pex. It seems to take forever… Any suggestion?

Copy code

$ ./pants run bin:xxx
⠠ 867.12s Building xxx.pex with 77 requirements: ...

How long does Pip take to install those same 77 requirements if you create a new virtual environment, clear the pip cache, and then run

pip install ...

in that venv? Alot less time or comparable?

How do I get all those requirements?

Presumably they're in a requirements file or a project.toml file you already told Pants about with a BUILD target.

But easiest is probably to re-run Pants with the

--no-process-cleanup

option. That will print a line just before the "Building xxx.pex" line telling you where that action's sandbox directory is. You can look at the contents of the

__run.sh

file in that directory to see the command Pants is running. That will list all the requirements.

I just followed your instruction and pip install in a venv, and I got this:

This should be the root cause that it stuck

Ok. Does that mean you know what to do then to re-work your deps to not need that version of rsa?

yep! I have to pin that rsa version.
