Now you have successfully installed the Python Virtual Environment. The next is how to create a virtual env.

Make a directory where you want to setup this virtual env. And follow the commands.

This is a example. I have created a directory named environments and inside that directory I have created a virtual-env named project1.

mkdir environments;

cd environments;

virtualenv project1;

This is the command to activate the virtual-env

source project1/bin/activate

Now you are successfully activated the virtual-env. You can see your project name in you terminal.

To deactivate and come out of the virtual-env using this command

deactivate

If you need to access this virtual-env you can go back to the last directory and activate it using the last command we used to activate.
