It may be a SSL error. Could you tell us which operating system you are running, as well as the output of `python -c "import ssl; print(ssl.OPENSSL_VERSION)"` — H. Gourlé, Apr 10 '18 at 05:36

As shown in the error log, this is the cause:

403 Client Error: TLSv1.2+ is required for url: https://pypi.python.org/simple/django/

As mentioned in this answer, you need to upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

What's happening: Python.org sites are stopping support for TLS versions 1.0 and 1.1. This means that Mac OSX version 10.12 or older will not be able to use pip unless they upgrade pip as above.

(Note that upgrading pip via pip install --upgrade pip will also not upgrade it correctly)

This thread explains it (thanks to this twitter post):

Mac users who use pip and PyPI:

If you are running macOS/OS X version 10.12 or older, then you ought to upgrade to the latest pip (9.0.3) to connect to the Python Package Index securely:
curl https://bootstrap.pypa.io/get-pip.py | python
and we recommend you do that by April 8th.

Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS < 10.13. Official release notes: https://pip.pypa.io/en/stable/news/

To avoid other install errors, make sure you also upgrade setuptools after doing the above:

pip install --upgrade setuptools
