Can't indicate minimum python version in pipenv file

I’m trying to indicate the minimum python version in my Pipfile. I’ve got

[requires]
python_version = "3.5"

but if you run that on Python 3.6, pipenv check will fail. I’ve tried specifying python_version = ">=3.5", or >3.5, but both also fail.

How do I do this, or am I missing something?

@gpakosz yes I would, reopening

You can only specify exact versions currently. Delete the whole section if you want it to work on multiple versions, it’s just for pinning.
