how to fix ModuleNotFoundError: no module named bs4

Question

I am trying to create a program that takes a set of numbers from a webpage and adds them up together. I used the beautifulsoup module that I installed(ran "pip install beautifulsoup4 in command prompt).

Code:

from bs4 import BeautifulSoup
web=request.urlopen('http://py4e-data.dr-chuck.net/comments_845350.html').read()
x = BeautifulSoup(html)
tags=x('span')
sum=0
for tag in tags:
    sum = sum+int(tag.contents[0])
print(sum)

However, whenever I run the program, python gives me a ModuleNotFoundError: no module named bs4. How can I fix this?

Answer 1

If you look here , you see that pip install beautifulsoup4 should do the job.

If you are on Linux you might have to use pip3 instead.

Answer 2

Do you have more than one version of Python installed on your machine?

If so, try running

pip --version

Will return something like this

pip 18.1 from c:\...\lib\site-packages\pip (python 3.6)

Then verify if you are using the same version to run your script
