A python3 virtualenv and am trying to create Django project. I see "ERROR:root:code for hash md5 was not found" with python2.7 mentioned in the error?

Question

I created a virtualenv with python3 -m venv env, activated env. which python and python --version confirm my environment is active and running Python 3.6.1. I then went to install django with pip install django. Then django-admin startproject project this command creates a the project but returns the following:

ERROR:root:code for hash md5 was not found.

I then ran

cd project
django-admin startapp account

Same thing, created the app but returned this same error/warning.

I notice that python2.7 shows up a lot in this error. When I activate env and enter the interactive console it shows it running python 3.6, not sure what is going on here. These commands are doing what they are supposed to but throwing this error, so not even sure if it is something I should worry about? Thanks for any help.

Edit: I feel like I have created python3 virtual environments and set up django projects without an issue many times. Recently deployed my first project and am thinking maybe I could have screwed something up on my machine? I see other questions related to this error referring to ssl... I tried brew unlink openssl as recommended here ERROR:root:code for hash md5 was not found - not able to use any hg mercurial commands but that did not work.

Lastly sorry for the poorly worded title I had to try and convey the problem in 150 characters.

`which python` will show you if `source env/bin/activate` has worked. — Keith John Hutchison, Mar 04 '20 at 20:35
@KeithJohnHutchison did not know this but it returns `/Users/justin/Desktop/social/env/bin/python` so it using the environment — Justin, Mar 04 '20 at 20:36
`python --version` will confirm what version of python you have activated — Keith John Hutchison, Mar 04 '20 at 20:42
@KeithJohnHutchison `Python 3.6.1`... seems this error is all over the internet. None of the solutions I've seen have helped but looks like a python issue not a django issue? — Justin, Mar 04 '20 at 20:43
Strange. try using pip3 explicitly if `pip3 --version` shows the correct path. — Keith John Hutchison, Mar 04 '20 at 20:51
I used pip3 explicitly to globally install certbot to get around an openssl issue this week. — Keith John Hutchison, Mar 04 '20 at 20:52
You could try updating python3 as well. I'm on 3.7.6. The latest is 3.8.2. — Keith John Hutchison, Mar 04 '20 at 20:55
That returned `pip 20.0.2 from /Users/justin/Desktop/social/env/lib/python3.6/site-packages/pip` . Tried creatring a new env/project using pip3, no effect. Will try upgrading python, thanks for your help so far. — Justin, Mar 04 '20 at 20:58
I just got similar errors with `virtualenv -p python3 env-test-for-justin` but django installed with `source env-test-for-justin/bin/activtate` and `pip install django` with no issues. — Keith John Hutchison, Mar 04 '20 at 21:20
@KeithJohnHutchison I'm confused on what you are saying. You got a similar error, but django installed regardless? — Justin, Mar 04 '20 at 21:27

python@2.7 is no longer supported by brew.

I got rid of the error message by removing the brew python 2.7 and then installing virtualenv with sudo pip3.

Note this will cause issues with any legacy projects on your device that uses brew python 2.7 virtual environments.

brew uninstall python@2.7
sudo pip3 install virtualenv

I had a similar issue with creating a new environment.

However ... installing django worked.
