Pipenv tries to resolve packages where their markers evaluates to false
See original GitHub issueIssue description
In Pipfile, packages that were expected to become a dependency only if marker expressions evaluates to true, has unexpectedly become a dependecy when markers evaluates to false
Expected result
Packages won’t be resolved and installed under environment where markers evaluates to false.
Actual result
Pipenv tries to resolve those packages
Steps to replicate
OS is Archlinux
mkdir -p ~/temp
cat > ~/temp/Pipfile <<EOF
[packages]
pywin32 = {version = "==227", markers="sys_platform == 'win32'"}
EOF
pipenv install --verbose

I, too, am running into this issue… except I have
pywin32 = {version = "*", markers = "platform_system == 'Windows'"}
Same error, though.
@frostming I’m sorry but I don’t quite understand your meaning of “generate correctly for all possible platforms”. How does it have anything to do with platform-specific markers?
