How to activate a virtual environment in Ubuntu?

Question

I installed virtualenv and I created a virtual environment inside my directory. Everything is OK, but I can't activate it. When I run:

source /bin/activate

it says:

already: command not found

A virtualenv only works in a specific directory. You get to specify the directory when you create the venv. This does not seem like an Ubuntu-related question. This seems like a how-do-I-use-python-venv question. There are some good examples at docs.python.org/3/library/venv.html. — user535733, Mar 31, 2021 at 15:52

You need to install python3-venv:

sudo apt install python3-venv

Then:

python3 -m venv vvv
source vvv/bin/activate

if your virtual environment name is "venv", you can use below command to switch there:

source venv/bin/activate

This seems like a duplicate of another answer to this question. How is this answer different?
