ERROR: No matching distribution found for XXX (where XXX should be excluded by sys_platform)

Issue description

Pipenv fails to lock Pipfile.lock if Pipfile contains entries where sys_platform does not match.

Expected result

Locking should work like it did previous releases

Actual result

There was a change when we dropped requirementslib to try and make sys_platform locking include sub-dependencies, but if you want it to be truly skipped you can convert it to a marker -- for example: pywin32 = {version = "*", sys_platform = "== 'win32'"} --> pywin32 = {version = "*", markers = "sys_platform== 'win32'"}

Sorry for the trouble!

[bearsh]

thanks @matteius, that seems to work.

maybe the doc should be updated to reflex that change...

Hello @matteius ,

When converting sys_platform to a marker, it solved the error when it had to be excluded (e.g. macOS, linux). But, it introduces an error when it has to be included (running Windows).

When using pywin32 = {version = "*", sys_platform = "== 'win32'"} on Windows, it works just fine.

When using pywin32 = {version = "*", markers = "sys_platform == 'win32'"} on Windows Server 2022, it gives me:

[pipenv.exceptions.InstallError]: ERROR: Could not find a version that satisfies the requirement pywin32== (from versions: 302, 303, 304, 305, 306)
[pipenv.exceptions.InstallError]: ERROR: No matching distribution found for pywin32==
ERROR: Couldn't install package: {}

Any hint to solve this issue on linux without introducing an error on Windows?

Thank you!

Problem solved

To solve this on all platforms, I was forced to specify some version rather than *.

i.e.: pywin32 = {version = ">=306", markers = "sys_platform == 'win32'"}

With this, the Pipfile.lock file included the following snippet:

"pywin32": {
    "markers": "platform_system == 'Windows'",
    "version": "==306"
},

It seems that the "version": "==306" was needed on Windows to successfully install pywin32
