Let us take a closer look at how to Activate Virtualenv Digitalocean with the support of our DigitalOcean Managed Services at Bobcares.

What is Virtualenv Digitalocean?

An environment in Python is a folder (directory) that contains everything that a Python project (application) requires to run in an organized, separate manner. When launched, it automatically includes its own Python interpreter – a clone of the one used to generate it – as well as its own pip.

Virtualenv solves a variety of issues, including:

• Making a new, separate environment for a Python project

• The ability to download packages without requiring administrative or sudo capabilities.

• Simple application packaging

• Creating a list of dependencies for a single pip-created project.

• Using a requirements file prepared with pip, we can easily retrieve the de</mark>pendencies.

• Giving way to cross-system portability

Regardless of how many Python projects we have, working using virtualenv is the recommended method. It is incredibly simple to use and a fantastic tool to have on hand. When used with pip, it truly works wonders.

Install and activate virtualenv on digitalocean

We can have a separate location on the server for Python projects by using virtual environments. We’ll use venv, which is part of the standard Python 3 library and can be installed by typing:

sudo apt install -y python3-venv

Create a Virtual Environment

Using the pyvenv command, we can establish a new environment. In this case, we’ll refer to the new environment as my env.

python3 -m venv my_env

Activate Virtual Environment

Use the command below to activate the environment, where my env is the name of the programming environment.

source my_env/bin/activate

The command prompt will be prefixed with the environment name as shown below:

# (my_env) [root@layerstack environments]#

Test Virtual Environment

Start the Python interpreter by typing in the following:

python

When we get the following output, we know we’re in the interpreter:

Python 3.8.2 (default, Mar 13 2020, 10:14:16) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

Now, write the classic Hello, World program using the print() function:

print("Hello, World!")

Output:
Hello, World!

Deactivate Virtual Environment

Terminate the Python interpreter:

quit()

Then, quit the virtual environment by typing in the following code:

deactivate
