This is related to https://github.com/pantsbuild/pants/issues/14983, but when a pex depends on a distribution, does that do something funny with the module used for 
entry_point
? I'm seeing my module specified as 
entry_point
somehow end up in a traceback like 
/home/nathanael/.pex/installed_wheels/64f793b8414b45d023fab18cdb41b8298ed2f8d103ec032118f40b5ad1289e2f/my_distribution-0.0-py3-none-any.whl/path/to/my_module.py
When I remove the dependence on the distribution, the built pex goes back to using the module I expect it to (and not some older form of it like I mention in the ticket)
I can actually get around it for now by not depending on a distribution and doing something different, but pretty odd nonetheless
e
From a PEX standpoint the entrypoint is just looked up on the sys.path. If its present in mulltiple distributions / loose source on the sys.path, the leftmost sys.path entry where it exists should win.
h
That makes sense. It feels like the build process is inserting it erroneously, though. Since I don't see any linking between 
my_distribution
and 
my_module.py
e
But if we've got code included multiply on the sys.path, that's a losing proposition generally. C.F.: Discussion about versions today and the JVM.
SO you're saying 
my_distribution
comes from a 
python_distribution
target and the transitive file deps of that target should not include 
my_module
?
h
Yes and that's what my use of 
./pants dependencies --transitive
seems to be telling me
e
Huh. So then this bug report can be unmuddied - the package goal is doing the wrong thing on your 
python_distribution
target then.
h
I wouldn't quite say that. When I build and inspect the package, I don't see 
my_module.py
included.
So I think 
./pants package //:my_distribution
does the right thing
e
Huh - that is very strange then.
Internally when a 
pex_binary
depends on a 
python_distribution
the rules that power the 
package
goal should be exactly what are run on the 
python_distribution
before it gets added to the PEX file.
That's definitely worth filing a targeted bug at.
The narrower and more detailed you can get a repro, the better of course.
h
Okay, I'll try to detail that out better. Thanks for providing a gut check on it.
