morning (PST morning that is) all, hey if want to debug a failure while generating a lock file, how would i do that? Retaining the sandbox:

Copy code

pants -ldebug --keep-sandboxes=always generate-lockfiles

and then executing the generated file

__run.sh

outputs the same truncated error message.

it seems like pants uses

pex lock

to generate the lock files, is there a way can run something like

pex lock --debug

somewhere so I can see the whole output?

new to pex as well not even sure if

--debug

is a supported flag for pex

you can provide

PEX_VERBOSE=9

😉

also, there’s a flag to tell pex to preserve the pip log file, which can be helpful as well. search this slack, it’s come up a few times before.

will do, by PEX_VERBOSE, do you mean this

Copy code

PEX_VERBOSE=9 pants -ldebug --keep-sandboxes=always generate-lockfiles

or do you mean edit the

.__run.sh

and add the env var

I do think both works, but I don’t recall if pants will preserve it or not when invoking pex. The latter is a safe bet, though.

ok it seems like pants does not preserve in-line env vars, but manually ediiting the file did

yea, so it wasn’t on the allow list by default then..
