Python2/3 is a mess

I only install pip once and using Python3. Then I pip install virtualenv. Then I create and activate a Python2 virtual environment. Once activated, I can pip install python 2 packages as needed without needing to download some kind of Python2 version of pip.



Here's my notes:

To verify virtualenv is installed and version is using **Python3**:
1. user $ virtualenv --version
2. If not:

    user$ sudo apt install virtualenv

To create a new virtualenv in **Python3**:

    user$ virtualenv ~/.virtualenvs/3/[name of new virtualenv]

To create a new virtualenv in **Python2**:

    user$ virtualenv -p /usr/bin/python2 ~/.virtualenvs/2/[name of new env]

To activate an existing virtualenv:

    user$ source ~/.virtualenvs/2/[folder of virtualenv]/bin/activate

To de-activate the virtualenv in use:

    user$ deactivate

Running a pip -V after the virtual environment has been activated is an easy check to make sure it will do what you want.
