`--extra-pip-args` doesn't pick up `--platform` option for `pip` correclty.

[ChannyClaus]

Issue description

--platform flag (along with --no-deps and --target) from pip doesn't seem to get picked up correctly by pipenv via --extra-pip-args.

Expected result

The installation should succeed since pip install does with those flags:

$ pip install --platform=macosx_10_14_x86_64 --no-deps --target $(pipenv --venv)/lib/python3.8/site-packages/ tensorflow~=2.8.0

[ChannyClaus]

took a quick look at the code - seems like this flag isn't passed down to the locking function https://github.com/pypa/pipenv/blob/main/pipenv/routines/install.py#L648-L655

is pipenv not designed to handle the case where the user is trying to masquerade a platform different from the one they are running pipenv on? (i'm trying to create a lock for Pipfile where the dependencies exist only for x86-64, i.e. not for arm64)

[matteius]

@ChannyClaus I opened a PR that I believe addresses it. #6006
I don't think you'll need to pass --no-deps since we already pass this as part of pipenv installation.

[ChannyClaus]

@ChannyClaus I opened a PR that I believe addresses it. #6006 I don't think you'll need to pass --no-deps since we already pass this as part of pipenv installation.

hmm does the command above pipenv install --verbose --extra-pip-args "--platform=macosx_10_14_x86_64 --no-deps --target $(pipenv --venv)/lib/python3.8/site-packages/" tensorflow~=2.8.0 work with the change? i just tried it out locally and it seems to be failing still.

[matteius]

Well I wouldn't pass --no-deps because as I said we already pass that by default, but I wasn't able to get it to work with the specifier ~=2.8.0 but removing that it did work.

[ChannyClaus]

yeah i think making it work with the specifier is critical - at least for the use case we have a bunch of apple silicon macbook, i.e.

In [1]: import platform

In [2]: platform.machine()
Out[2]: 'arm64'

users working with a Pipfile that pins tensorflow at ~=2.8.0. not exactly sure how pipenv lock works under the hood but if it's using pip under the hood it supposedly should work since pip install tensorflow~=2.8.0 works with the flags in the PR description.

[matteius]

Well something is wrong with that version for it to be resolved, version specifiers in generally are working.

[matteius]

Actually my reason it wasn't resolving is I have default python 3.11 and that version only goes up to 3.11 -- when I run this it works:

$ pipenv install --verbose --extra-pip-args "--platform=win_amd64 --target C:\\c\\Users\\matte\\.virtualenvs\\issue-6001-WKuyds7q\\Lib\\site-packages\\"  tensorflow~=2.8.0 --python 3.10

[matteius]

The other thing my PR does not address is how to store extra pip args in the Pipfile for future relocking so it doesn't have to be supplied on the CLI everytime. Also I am pretty sure in my PR i haven't exposed it directly to the lock command yet but that should be easy enough to add.
