ImportError: No module named 'bs4' with virtualenv python3 - python

I know this is a common issue but I still can't figure how to make it work.
I'm trying to use bs4 inside a virtual environment but I have this error ImportError: No module named 'bs4'
I have my virtualenv activated :
pip install bs4
Requirement already satisfied: bs4 in /home/****/.virtualenvs/****/lib/python3.5/dist-packages
Requirement already satisfied: beautifulsoup4 in /home/****/.virtualenvs/****/lib/python3.5/dist-packages (from bs4)
My scripts start with
!/usr/bin/python3.5
# -*-coding:Utf-8 -*
import json
import hashlib
from bs4 import BeautifulSoup
Any help is welcome !

Are you sure you are using the right python? If you have everything tied up in a virtual environment, then you need to be using python from inside that virtualenv. The command:
which python
at a bash prompt should tell you what the command:
python
points to.
From the look of your script, you are asking it to go to /usr/bin/python3.5, which is not the directory of your virtualenv, by looking at your path, it is somewhere in your home directory. Try changing the path in your script to the python virtualenv version (the one which pip has found bs4 in).

failed to use urllib.request with python in vscode

I tried to import urllib.request wth python in vscode but kept getting the message: ImportError: No module named request. I have no problem importing just urllib, which I know is the right line for python2. I'm sure I'm using python3 as that's what I've selected in the interpreter path.
Here's the screenshot:
I've also put pip3 install urllib3 in the terminal and got this message which means python3 should have it:
Requirement already satisfied: urllib3 in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (1.26.9)
any idea what have gone wrong or it's not the problem with python version?
This is related to your multiple environments. You should specify the installation path when using pip installation package.
pip install -t flodername urllib3 #the package of the python interpreter you chosen

ModuleNotFoundError: No module named '...'

I'm trying to install a few packages (beautifulsoup4 and requests) for a project.
I installed these packages by running these commands in the terminal on macOS:
pip3 install beautifulsoup4
pip3 install requests
both did install successfully.
Now if I open my project in PyCharm, I can import the modules by using:
from bs4 import BeautifulSoup
import requests
Both packages are imported successfully and can be used in my code.
To be sure everything was installed correctly, I looked at the venv/lib/Python3.10 folder. beautifulsoup4-4.10.0.dist-info, bs4, requests and requests-2.27.1.dist-info are present.
However, when I run the CGI script (Python), I get the following error in the terminal:
from bs4 import BeautifulSoup
ModuleNotFoundError: No module named 'bs4'
Even when I open a new terminal window and run the following commands:
python3
>>> from bs4 import BeautifulSoup
it runs fine without any errors.
The same issue happens for the requests package.
I also ran pip3 install bs4 but that also didn't fix anything.
I found what caused the issue. bs4 and requests were both installed correctly but in my CGI script, I used the wrong Python path. I had to change #!/usr/bin/python3 to the path that which python3 gave me.
I would recommend to always install packages using python3 -m pip install <name_of_the_package>. In this way you can be sure that you are using the correct pip.
To make sure that the python you a using really has the packages installed, try python3 -m pip list.
If all is good, check if the python interpreter the pycharm is using in your project is the right one.
It sounds to me that in pycharm you're using a virtual environment, but when you are using python3 at the terminal, you a using the main installation.

Python: ModuleNotFoundError: No module named 'requests'

I have begun learning to program (in general, and in Python), and I am trying to import a module. I have installed it (using pip install --user requests) and the folder appears in my file explorer. When I try to import requests now inside IDLE, I get a ModuleNotFoundError.
I have tried adding the folder to the PATH environment variable, although I am not sure I understand what this means, but it did not work. What can I do?
If "pip freeze" lists the module, then one option will be to close the idle and type the following at the command prompt/terminal.
python -m idlelib
New IDLE will start and it should be possible to import the module.
That means that the installation you made was not done properly, so when you type in requests to get the module in your script it cannot find it.
Just reinstall it properly with (if the prompt for the python version you want to use is simply python):
python -m pip install requests
EDIT:
Adding to this, based on the comment of #AST :
Indeed, if you get Requirement already satisfied when using the above command, you can first delete requests with the following command, and then try the installation command.
pip uninstall requests

import bs4 ModuleNotFoundError: No module named 'bs4'

I am trying to create a web script, but when I run it it gives me this error:
import bs4 ModuleNotFoundError: No module named 'bs4'
When I go to my project interpreter, bs4 and beautifulsoup4 are installed. Also, when I run the command pip install beautifulsoup4, it says that:
Requirement already satisfied: soupsieve>1.2; python_version >= "3.0" in ./venv/lib/python3.8/site-packages (from beautifulsoup4) (2.1)
My Python version is 3.8.0.
Try to run this command in the same interpreter as your python script.
pip install beautifulsoup4
You may have more than one interpreter setup on your machine, and when you type the command it does not install to the interpreter/virtual environment where your python script is running.
Solution
Follow the following steps in order, if applicable to your situation:
If you are using an IDE, such as Pycharm or VSCode, you will have an option to choose your virtual environment. Keep note of the name of the environment.
Then, activate your virtual environment, and install the package using the command I specified above. This process can be done from the command line or IDE
Run your python script in that environment/interpreter
This should have liberally answered the question, but if you want to learn more about virtual environments and interpreters, then use this link.

I use PyCharm Python3.7 , is ok.
Python3.8 should be fine.
pip3 install beautifulsoup4
from bs4 import BeautifulSoup

Installing python package

I've already installed mechanize using pip install mechanize, such that when I enter it in the command prompt, the response is: Requirement already satisfied: mechanize in c:\users\wwl\anaconda3\lib\site-packages.
However, when I type import mechanize in the jupyter notebook, it gives an error:
ImportError: No module named '_mechanize'.
Where have I gone wrong?
Are you using Virtualenv?
If so, make sure you are importing the global libraries to your virtualenv (https://virtualenv.pypa.io/en/stable/userguide/#removing-an-environment).
If not, probably your Python version is not compatible. https://stackoverflow.com/a/24001585/2051397
Hope it helps
