Python/virtualenv

venv

Create virtual environment:

python3 -m venv [project_name]

This will create a folder called "[project_name]"

To use the folder:

source [project_name]/bin/activate

Then pip install whatever you want

To deactivate the virtual env: (from within the virutalenv)

deactivate

Create env with particular python:

virtualenv -p $(which python2) [project]

Activate:
