sys_platform = "== 'win32'" no longer works

[VonAncken]

Issue description

We are building our project for different platforms, but we have modules that should only be installed on certain platforms. So far we have used the following notation:

sys_platform = "== 'win32'"

This worked fine with release 2018.11.26, but not with release 2020.5.28 anymore.

Expected result

A module with the limitation for a certain platform should not be installed on all other platforms.

Actual result

The limitation for a certain platform is ignored.

Steps to replicate

Write a module with the restriction for a specific platform in the notation sys_platform = "== 'win32'" into a pipfile and install pipfile.

Please fill out the entire bug report including your Pipfile where you are having this issue. I cannot reproduce this issue locally.

To confirm, this is not specified in the report, but this is about using this syntax in a Pipfile, correct?

I think I am also having this issue with sys_platform = "== 'Linux'".

Here is a Pipfile which works on pipenv==2018.11.26 but fails with pipenv==2020.6.2:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[packages]
google-python-cloud-debugger = {version = "*",sys_platform = "== 'Linux'"}

[dev-packages]

[requires]
python_version = "3.7"

Just chiming in to say I'm seeing this issue too

[frostming]

@dhendry the issues don't look the same. Did you access pypi behind a proxy? Was https://pypi.org/simple reachable?

[dhendry]

@frostming No proxy, no problems with other packages, pypi.org is reachable:

[dhendry]

Any update on this? Its pretty annoying

@frostming you earlier commented that the issues do not look the same. Do you want me to open a new issue?

@techalchemy This issue still has a Status: Needs More Information label. I believe I have included a simple example to reproduce the issue. Is there any additional information I could provide to help you out?

[Dhruvacube]

any updates?

[matteius]

Sorry, I do not have an update at this time. Possibly related: https://github.com/pypa/pipenv/issues/5239

[matteius]

I would ask, could this be rechecked with pipenv==2022.8.19 and if possible provide a reproduction example?
