When running pex, is there a way to redirect the pip log output to stdout when running pex? sometimes it prints backtracking warnings and would be nice see them on the console.

try

PEX_VERBOSE

env var.. https://pex.readthedocs.io/en/latest/api/vars.html#PEX_VERBOSE

I think the answer is no. @curved-television-6568 may be right at verbosity 9 level, but IIRC you must use

--preserve-pip-download-log

to get the log retained in a file to look at after the fact.

with

PEX_VERBOSE

I have seen the internal pex command that exposed the

--log /path/to/pip.log

which is how i found the problem. however we often run these in an automated environment and a

--pip-log-to-stdout

would be useful.

You should file a feature request. This is not as easy as it seems since Pex needs the full verbose Pip log for analysis. There is a Pex log tailer / tee implementation though for groundwork.
