Python: No module named 'BeautifulSoup'

This might be a super newbie question but I am trying to import BeautifulSoup to my python project:
import urllib.request
from bs4 import BeautifulSoup
but I am getting this error:
import BeautifulSoup
ModuleNotFoundError: No module named 'BeautifulSoup'
From what I am reading I have to install it make a child folder for it? If so why do my other imports such as import urllib.request work without installation and this one doesn't?

Python comes with a default set of modules - you can see that urllib is included with your installation of Python by looking at the list of default modules on this page.
You should follow these instructions to download and use pip, the Python package manager and installer, to get and install the BeautifulSoup module.

Module requests Python

I am trying to use the requests module in a python script. I start by the import command and write the script however it is telling me that requests is not a module. Can anyone explain this to me? Is this not built in like "re" or do I have to import it in? I am new to python so any help would be great. Using Windows!
Thanks

No, requests is a 3rd party library. You can install it using pip.
pip install requests
And even if re is built-in, you have to import it in order to use it.

Python 2.7.10 error "from urllib.request import urlopen" no module named request

I opened python code from github. I assumed it was python2.x and got the above error when I tried to run it. From the reading I've seen Python 3 has depreciated urllib itself and replaced it with a number of libraries including urllib.request.
It looks like the code was written in python 3 (a confirmation from someone who knows would be appreciated.)
At this point I don't want to move to Python 3 - I haven't researched what it would do to my existing code.
Thinking there should be a urllib module for Python 2, I searched Google (using "python2 urllib download") and did not find one. (It might have been hidden in the many answers since urllib includes downloading functionality.) I looked in my Python27/lib directory and didn't see it there.
Can I get a version of this module that runs on Python27? Where and how?

Try using urllib2:
https://docs.python.org/2/library/urllib2.html
This line should work to replace urlopen:
from urllib2 import urlopen
Tested in Python 2.7 on Macbook Pro
Try posting a link to the git in question.

You can program defensively, and do your import as:
try:
from urllib.request import urlopen
except ImportError:
from urllib2 import urlopen
and then in the code, just use:
data = urlopen(MIRRORS).read(AMOUNT2READ)

from urllib.request import urlopen, Request
Should solve everything

Instead of using urllib.request.urlopen() remove request for python 2.
urllib.urlopen() you do not have to request in python 2.x for what you are trying to do. Hope it works for you.
This was tested using python 2.7 I was receiving the same error message and this resolved it.

Change
from urllib.request import urlopen
to
from urllib import urlopen
I was able to solve this problem by changing like this. For Python2.7 in macOS10.14

You are right the urllib and urllib2 packages have been split into urllib.request , urllib.parse and urllib.error packages in Python 3.x. The latter packages do not exist in Python 2.x
From documentation -
The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.
From urllib2 documentation -
The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error.
So I am pretty sure the code you downloaded has been written for Python 3.x , since they are using a library that is only present in Python 3.x .
There is a urllib package in python, but it does not have the request subpackage. Also, lets assume you do lots of work and somehow make request subpackage available in Python 2.x .
There is a very very high probability that you will run into more issues, there is lots of incompatibility between Python 2.x and Python 3.x , in the end you would most probably end up rewriting atleast half the code from github (and most probably reading and understanding the complete code from there).
Even then there may be other bugs arising from the fact that some of the implementation details changed between Python 2.x to Python 3.x (As an example - list comprehension got its own namespace in Python 3.x)
You are better off trying to download and use Python 3 , than trying to make code written for Python 3.x compatible with Python 2.x

For now, it seems that I could get over that by adding a ? after the URL.

Cannot import Beautiful Soup

I am trying to use BeautifulSoup, and despite using the import statement:
from bs4 import BeautifulSoup
I am getting the error: ImportError: cannot import name BeautifulSoup
import bs4 does not give any errors.
I have also tried import bs4.BeautifulSoup and just importing bs4 and creating a BeautifulSoup object with: bs4.BeautifulSoup()
Any guidance would be appreciated.

The issue was I named the file HTMLParser.py , and that name is already used somewhere in the bs4 module.
Thanks to everyone that helped!

I found out after numerous attempts to solve the ImportError: cannot import name 'BeautifulSoup4' that the package is actually called BeautifulSoup so the import should be:
from bs4 import BeautifulSoup

Make sure the directory from which you are running your script does not contain a filename called bs4.py.

I solved it by installing beautifulsoup4, the "4" is essential.
pip install beautifulsoup4

I experienced a variation of this problem and am posting for others' benefit.
I named my Python example script bs4.py
Inside this script, whenever trying to import bs4 using the command:
from bs4 import BeautifulSoup, an ImportError was thrown, but confusingly (for me) the import worked perfectly from an interactive shell within the same venv environment.
After renaming the Python script, imports work as expected. The error was caused as Python tries to import itself from the local directory rather than using the system copy of bs4

Copy bs4 and beautifulsoup4-4.6.0.dist-info from C:\python\Lib\site-packages to your local project directory. It worked for me. Here, python actually looks for the library in local directory rather than the place where the library was installed!

The bs4 and beautifulsoup4 folders might be in the site-packages folder. So copy BeautifulSoup4 folder in bs4 and then try the below code. It worked for me.
from bs4 import BeautifulSoup
Since you were importing BeautifulSoup from bs4 and in bs4 there was no BeautifulSoup folder. That is why it was showing ImportError: cannot import name BeautifulSoup.

One of the possible reason: If you have more than one python versions installed and let's say you installed beautifulsoup4 using pip3, it will only be available for import when you run it in python3 shell.

I was also facing this type error in the beginning even after install all the modules which were required including pip install bs4 (if you have installed this then no need to install beautifusoup4 | BeautifulSoup4 through pip or anywhere else it comes with bs4 itself)
Solution : Just go to your python file where it is installed C:\python\Lib\site-packages
and then copy bs4 and beautifulsoup4-4.6.0.dist-info folders and paste it to your project folder where you have saved your working project.

The best way to resolve is, while creating your interpreter select your global python path on your system(/usr/local/bin/python3.7).
Make sure that in pycharm shell, python --version appears as 3.7. It shouldn't show 2.7

There is no problem with package just need to Copy bs4 and
beautifulsoup4-4.6.0.dist-info into your project directory

When I used
pip3 install beautifulsoup4
instead of
pip install beautifulsoup4
it returned that all requirements already satisfied but I ran it again and it worked, I'm using a virtualenv which uses python 3.8.10, I don't really know the logic behind it but hey it worked.

I had the same problem. The error was that the file in which I was importing beautifulsoup from bs4 was in another folder. Just replaced the file out of the internal folder and it worked.

For anyone else that might have the same issue as me. I tried all the above, but still didn't work. issue was 1 was using a virtual environment so needed to do pip install in the pycharm terminal instead of a command prompt to install it there. Secondly I had typed import Beautifulsoup with the S not capitalized. changed to BeautifulSoup and it worked.

For me it was a permissions issue. Directory "/usr/local/lib/python#.#/site-packages/bs4" was only 'rwx' by root and no other groups/users. Please check permissions on that directory.

ImportError: No module named mechanize

I'm using easy_install, and I entered:
easy_install mechanize
and the last line it returned was:
Finished processing dependencies for mechanize
Now when I try to:
import mechanize
I get this error:
ImportError: No module named mechanize
Any idea what's wrong? Thanks

Have you checked sys.path in the python shell?
>>> import sys
>>> sys.path
# Returns a list of directories & .egg files
For python to find mechanize, it needs to be in one of the places listed on sys.path. If you know where mechanize was installed, then you can check directly whether it's on sys.path (I'm not sure how to find out where it was installed automagically).

This seems to be a pathing issue. These are fairly annoying. In my experience the best way to deal with them is to avoid them. You should look into using virtualenv. It will take care of python path issues for you.
