I keep getting the error message "ModuleNotFoundError"

I'm working on a Python project in which I scrape data from a website using the requests and BeautifulSoup modules. Yet, I continue to receive the problem message "ModuleNotFoundError: No module called 'bs4'". I attempted to install BeautifulSoup using pip, but it did not appear to work.

import requests
from bs4 import BeautifulSoup

url = 'https://www.example.com'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

This is the error message:

ModuleNotFoundError: No module named 'bs4'

I attempted pip install beautifulsoup4 in the terminal, but when I try to execute the script, I get the same error message.

Yet, despite my efforts, the outcome is not what I had hoped for. I came across this article that uses the example, but I'm not sure I got it right. Could you please help me?
