Hello!

./pants run

is interesting because it uses

InteractiveProcess

to run in the foreground, rather than running in a sandbox like normal. I don't think

--no-process-execution-local-cleanup

will do anything for the final run. Instead, you should see folders in the build root like

.pants.d/tmplpd86t9k

. Pants will write the PEX and relevant files to that folder and set

PYTHONPATH

appropriately
