Error Installing Django v2

Following the instructions on the Setup page, I am getting the following error:

Any version 2 gives the same error. Installing version 1 I get the following:

Checking the version, I get the following:

$ python -V
Python 2.7.15rc1

I followed the instructions as written, and while I can probably get this working, I thought the docs could be updated to address when the user has both versions of Python installed.

For those with multiple versions installed, the following worked for me:

$ virtualenv -p python3 venv
Running virtualenv with interpreter /usr/bin/python3

If you’re coming from Ruby-land and used to rbenv, I was told pyenv is analogous in that it will allow directory based versioning (I haven’t tested it).

Oh fun, my favorite part about programming — installation. 😅 Things change so quickly and my installation instructions need to be updated often. I’ll look into what I can improve. Thank you for the update!
