pipenv: Ignoring foo: markers 'bar' don't match your environment

Ignoring colorama: markers 'sys_platform == "win32"' don't match your environment

Ignoring funcsigs: markers 'python_version < "3.0"' don't match your environment

I’ve started getting the above errors whenever I install packages with pipenv into a pipenv created virtualenv.

I use the following command to install some base packages into each virtualenv:

❯ pipenv install --dev flake8 jedi importmagic epc autopep8 yapf pytest json-rpc service_factory autoflake hy isort bpython

Everytime I do, I get the warnings. It never used to be like that untill the recent homebrew python/python@2 updates. I don’t know if it’s got anything to do with it.
