How to create virtual env with python3

In Python 3.6+, the pyvenv module is deprecated. Use the following one-liner instead:

python3 -m venv <myenvname>

This is the recommended way to create virtual environments by the Python community.

To create virtual env

virtualenv -p python3 venv_name 

This will create new python executable in baseDirectory/bin/python3

How to activate newely created Venv:

cd baseDirectory/bin/  source activate  

Deactivate new venv

deactivate 

Python already ships with its builtin "virtualenv" called venv since version 3.3. You no longer need to install or download the virtualenv scripts for Python 3.3+.

Check that your installation provided the pyvenv command that should take care of creating the "virtualenv". Arguments are similar to the classic virtualenv project.
