问题
I am having issues with installing django and upgrading pip. I don't know how I began running into these issues, but when I go to type django-admin startproject mysite it gives me an error:
-bash: django-admin: command not found
I go ahead and type pip install Django and I then receive this error:
Could not fetch URL https://pypi.python.org/simple/django/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
When upgrading pip...

I believe the issue lies within [SSL: TLSV1_ALERT_PROTOCOL_VERSION]. I don't know how to go about fixing it so that I can use django and upgrade my pip version.
If I type python3 -c "import ssl; print(ssl.OPENSSL_VERSION)", I get OpenSSL 1.0.2n 7 Dec 2017. Do note that I was running django with no issues before these issues came to fruition.
回答1:
To upgrade pip, I typed into command prompt curl https://bootstrap.pypa.io/get-pip.py | python3.
To be able to run the django website on my machine, I had to use python3 manage.py runserver. The trick here was to use python3 instead of python.
