In this post, we will install the Flask web framework on Ubuntu Linux 20.04 inside a Python virtual environment.
If you don’t have a Python virtual environment, let’s create one. First, we need to install Python virtual environment tools using the following command.
sudo apt-get install python3-venv
Now that we have the virtual environment installed let’s create our first virtual environment (dev1) using the following command.
python3 -m venv dev1
After running the above command, we will have a directory called dev1
We can now activate the environment using the following code.
After activating the environment, we can install Flask inside using pip and the following command.
pip install flask
At this stage, we are done, and we can check that Flask is installed using the –version command.
The output is below.
