pipenv: CERTIFICATE_VERIFY_FAILED error when installing dependencies

Hi,

I have installed pipenv for the first time on my system by following the fancy installation method (because I have excellent taste!) and the world was a happy place to live in.

Then I went on running the following given the project I started to work on did not know about the wonders of pipenv:

pipenv install -r a_folder/requirements.txt

But then, suddenly the world was a sad place to live in. I got the following:

Requirements file provided! Importing into Pipfile…
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…

Is this expected?

Here’s some more info which I hope it will be useful:

$ pipenv --venv
/Users/my_user/.local/share/virtualenvs/the_project_folder-kENjJPUz

$ pipenv --version
pipenv, version 8.2.6

$ pipenv run python --version
Python 2.7.14

$ python --version
2.7.10

# My requirements.txt file
boto==2.48.0
fabric==1.14.0

# My automatically-generated Pipenv file
[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[dev-packages]

[packages]

boto = "==2.48.0"
fabric = "==1.14.0"

OS is macOS Sierra 10.12.4.

Anything you need to help troubleshoot this just let me know.

Thanks!
