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.

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
I am working with python flask's requests module. I have installed requests module using :
pip install requests
And verified that requests module exists when I run :
pip list
But when I run my python application , I receive import Error for requests module.
I noticed that pip is installing the module in C:\Users\xx\Documents\Projects\Python\Python3REST\lib\site-packages\ folder BUT the interpreter is looking for the module in C:\Users\xx\Documents\Projects\Python\Python3REST\lib\site-packages\flask\ folder.
I have tried running the command :
pip install --install-option="Path to install in" requests
But threw some other error.
The import error I am getting states :
ImportError: cannot import name 'requests' from 'flask'
(C:\Users\xx\Documents\Projects\Python\Python3REST\lib\site-packages\flask\__init__.py)
I am working in virtualenv in Windows 10.
I recently had the same problem installing a self made package. I installed it with pip install <package> and checked it was actually installed with pip list but running the script with import <package> returned a ModuleNotFoundError: No module named <package>.
I solved the problem creating an empty file called __init__.py in the package directory.
Check https://pythontips.com/2013/07/28/what-is-init-py/ and https://docs.python.org/3/tutorial/modules.html#packages for better understanding.
what if you add that folder to your path? using sys.path.extend?
I solved it using python3 -m pip install <package name>. In the OP's case, it should be python3 -m pip install requests.
Note that I'm using python 3.10.
I have never used Python before and am trying learn it on the fly. I have this file. I installed python 2.7 have added it the path. when I try python [filename].py I get errors saying
import requests,sys,csv,os,re,urllib2,urllib,time,traceback,string
ImportError: No module named requests.
Am I missing something here. Where would I find these and how do I get this running
You need to install the requests package:
pip install requests

I need to use urllib module in my code and I import it like this:
import urllib.request
import urllib.error
but PythonAnywhere returns the following error:
> No module named request
It looks like the urllib library is imported successfully when I try:
python3 myscript.py
instead of:
python myscript.py
But in this case I get another error:
> No module named 'pyvirtualdisplay'
Pyvirtualdisplay is also needed in my code, so I dont know what to do. Can someone help ?
The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error
~ urllib2 - python docs
When you run your script using
python myscript.py
Your system is using python2 which doesn't have the urllib.request and urllib.error modules. Use the urllib2 library.
You need to install Python extensions into each copy of Python that you use. For example, python and python3 use different set of extensions. You may have a script called pip3 that installs extensions into your copy of Python 3.
Installation instructions on the PyVirtualDisplay project page state that first you'll need to install pip and Pillow for Python 3. If you were using a Debian or Ubuntu VPS, these might work in a terminal:
sudo apt-get update
sudo apt-get install python3-pip python3-imaging
sudo pip3 install pyvirtualdisplay
But a Google search tells me PythonAnywhere is a web application hosting service. The list of supported extensions includes pyvirtualdisplay in Python 2 but not in Python 3. Just a guess, but the administrators may not be aware that pyvirtualdisplay has been ported. I'd recommend contacting PythonAnywhere support and requesting the extension's installation into Python 3.
You can install pyvirtualdisplay yourself for python 3. Either use a virtualenv (there are details on the help pages) or use the --user argument to pip and ensure you use the correct version of pip (pip3.3 or pip3.4 depending on the version you want to use)
I am trying to install BeautifulSoup4 and having trouble with pip. I have installed pip but when I go to run pip install BeautifulSoup nothing happens. Just a new line comes up on CMD
e.g.
C:\Python27\Scripts>pip install BeautifulSoup
C:\Python27\Scripts>
Anyone have any ideas? This is Windows 7 btw. May well be something obvious I'm missing as I'm really new to Python.
Thanks in advance.
Edit:
I should also add that when I then try from bs4 import BeautifulSoup I get the following error:-
ImportError: No module named bs4
Try these troubleshooting steps
1.Be sure you've followed all of these instructions carefully.
2.Check your path environmental variables to make sure you can run python from the command line.
3.Check your python DIRECTORY for the SCRIPTS folder. Look there to see if pip is there. I'm not 100 percent for sure but I think you must have pip here for it to be able to run from the command line.
By the way:
4.If you have python 3.4 or later, pip may already be installed.
if all else fails....
5.download this and run this in an admin cmd window:
python get-pip.py
6.try running the update commands if nothing else has worked.
pip install -U setuptools
7.er....switch to easy_install
