pipenv install produces ERROR: Could not find a version that matches django-dotenv

[dopatraman]

System details:
Ubuntu - 16.04
Python - 3.7
Pip - 9.0.1
Pipenv - 2018.11.26

This is my Pipfile

[[source]]
url = "https://pypi.org/simple"
name = "pypi"

[packages]
django-dotenv = "*"

[requires]
python_version = "3.7"

When I run pipenv install I get pipenv.exceptions.ResolutionFailure: ERROR: ERROR: Could not find a version that matches django-dotenv

Is it possible that djang-dotenv is not visible to pypi.org/simple?
