how to fix ModuleNotFoundError: no module named bs4

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?

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.

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

Installing BeautifulSoup on Pycharm

I am trying to install BeautifulSoup and this is the problem
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\PC\AppData\Local\Temp\pip-install-n8bpi4nt\BeautifulSoup\
This is the error I receive when I attempt to install BeautifulSoup
This is the code:
from bs4 import BeautifulSoup
import requests
search = input("Enter search term:")
params = {"q": search}
r = requests.get("https://www.bing.com/search", params=paramas)
soup = BeautifulSoup(r.text) # the text of the document passed into the class beautiful soup
print(soup.prettify())
This is the error:
from bs4 import BeautifulSoup
ModuleNotFoundError: No module named 'bs4'

In python 3 you need to install beautifulsoup4 (for mac/ubuntu): pip3 install beautifulsoup4 or (windows) pip install beautifulsoup4

You need to install the BeautifulSoup library on your machine.
Install it as follows:
pip install --user --no-cache-dir bs4 lxml # for python 2
or,
pip3 install --user --no-cache-dir bs4 lxml # for python 3
Installing modules for a user is a best practice to avoid global site-packages pollution

ImportError: No module named bs4?

I try to import library: from bs4 import BeautifulSoup.
When I run script I get error:
Traceback (most recent call last):
File "index.py", line 9, in <module>
from bs4 import BeautifulSoup
ImportError: No module named bs4
root#srvr [/home/public_html/grabber/similar]#
When I try install:
pip install beautifulsoup4
I get the following error:
Requirement already satisfied: beautifulsoup4 in /usr/lib/python2.6/site-packages/beautifulsoup4-4.5.1-py2.6.egg
Script is:
import sys
sys.path.append('/usr/lib/python2.6/site-packages')
from bs4 import BeautifulSoup

You installed BeautifulSoup for Python 2.6, but according to your tag, you are using Python 3.x. To install explicitly for Python 3, use pip3 instead of pip, i.e.
pip3 install beautifulsoup4

If you try this on Mac OS X do the following:
Go to the official website: http://www.crummy.com/software/BeautifulSoup/
Download the .tar.gz package
Unpack it
Go to the unpacked folder
Type: python setup.py install

If you use Pycharm, go to preferences - project interpreter - install bs4. If you try to install BeautifulSoup, it will still show that no module named bs4.

ImportError: No module named bs4 in Windows

I am trying to create a script to download the captcha from my website.
I think the code works except from that error, when I run it in cmd (I am using windows not Linux) I receive the following:
from bs4 import BeautifulSoup
ImportError: No module named bs4
I tried using pip install BeautifulSoup4
but then I receive a syntax error at install.
Here is the script:
from bs4 import BeautifulSoup
import urllib2
import urllib
url = "https://example.com"
content = urllib2.urlopen(url)
soup = BeautifulSoup(content)
img = soup.find('img',id ='imgCaptcha')
print img
urllib.urlretrieve(urlparse.urljoin(url, img['src']), 'captcha.bmp')
The problem according to this answer must be due to the fact I have not activated the virtualenv, and THEN install BeautifulSoup4.
I don't think this information will be of any help but I saved my python text in a notepad.py and the run it using cmd.

I had the same problem until a moment ago. Thanks for the post and comments! According to #Martin Vseticka 's suggestion I checked if I have the pip.exe file in my python folders. I run python 2.7 and 3.7 simultaneously. I didn't have it in the python 2.7 folder but in the 3.7.
So in the command line I changed the directory to where the pip.exe file was located. Then I ran "pip install BeautifulSoup4" and it worked. See enclosed screen shot.

I did a fresh install of Python 3.5 on my Windows 8.1 (64b) machine and then run:
C:\Users\Me\AppData\Local\Programs\Python\Python35-32\Scripts>pip install b

and then run:

test.py contains only:
from bs4 import BeautifulSoup
I received no error.

I could install bs4, but still got an error message like yours. My operation system is 64 bit, and I only had this issue after I installed the latest Python in "32 bit" version. So I removed the 32 bit one, then I can import the bs4 again, and it still works after I install the latest Python in 64 version. Hope it helps.

I have python3.7 32bit and python3.7 64 bit installed on Windows 10.
For this app, I am using the 32 bit version.
I was getting the following error:
ImportError: No module named bs4
when I was trying to 'import bs4' from my app.py. Someone said: "Make sure your pip and your python are both 32 bits", but omitted to explicitly say how, so here it is:
Delete your virtual environment if it exists.
Create a new venv using python -m venv venv, but explicitly call it from your 32bit python directory like this:
C:\Users\me\AppData\Local\Programs\Python\Python37-32\python -m venv my_venv
install the requirements by explicitly calling the 32bit version like this:
C:\Users\me\AppData\Local\Programs\Python\Python37-32\Scripts\pip install -r requirements.txt
That's it. I hope it works.

Beautiful Soup 4 Import

So I'm getting an import error on this line:
from bs4 import BeautifulSoup
It says:
ImportError: no module named 'bs4'
Any idea what's going on / how to fix this?
Thanks,

import sys; print(sys.path) shows that you use Python 3.3 but the output from pip shows that it installs for Python 2.7
Use pip that installs for Python 3.3. It might be already installed as pip3 or pip3.3. If not; then install it first.
