Pipenv: Package from Pipfile.lock ignored because of last (irrelevant) marker not matching

[dresnick-sf]

Issue description

This package is not installed though I'm running with python 2.7:

        "monotonic": {
            "hashes": [
                "sha256:23953d55076df038541e648a53676fb24980f7a1be290cdda21300b3bc21dfb0",
                "sha256:552a91f381532e33cbd07c6a2655a21908088962bb8fa7239ecbcc6ad1140cc7"
            ],
            "markers": "python_version == '2.6' or python_version == '2.7' or python_version == '3.0' or python_version == '3.1' or python_version == '3.2'",
            "version": "==1.5"
        }

The output from pipenv:

Ignoring monotonic: markers 'python_version == "3.2"' don't match your environment

Expected result

A package with markers matching my version of python to be installed.

Actual result

When running with -v I see this as it is installing:

Installing "monotonic==1.5; python_version == '3.2' --hash=sha256:23953d55076df038541e648a53676fb24980f7a1be290cdda21300b3bc21dfb0 --hash=sha256:552a91f381532e33cbd07c6a2655a21908088962bb8fa7239ecbcc6ad1140cc7"

Steps to replicate

Building this Dockerfile shows the problem.

FROM ubuntu:xenial-20180525

RUN set -x \
    && DEBIAN_FRONTEND=noninteractive \
    && apt-get update \
    && apt-get -y --no-install-recommends install \
        python-pip \
        python-setuptools \
    && pip install --upgrade pip==10.0.1 pipenv==2018.7.1 \
    && apt-get clean
WORKDIR /home
RUN set -x \
    && pipenv install monotonic \
    && cat Pipfile.lock \
    && pipenv --rm \
    && rm Pipfile* \
    && pipenv install click coloredlogs \
    && pipenv --rm \
    && pipenv install --deploy --system
RUN pipenv --support

The key part of the output:

+ pipenv install --deploy --system
Installing dependencies from Pipfile.lock (fe9a7a)...

This works as expected with v2018.05.18.

Hi! Could you help verify whether this happens at 2018.6.25? It would help us a lot to pin down exactly what change caused this issue. Thanks! Also, sorry for the bug :(

[dresnick-sf]

It has the same error on 2018.6.25.

[uranusjr]

I see, thanks so much! We’ll investigate.

the debugging info on here is actually super helpful, I think I know exactly why this is happening and how to fix. Thanks for reporting
