ImportError: No Module Named bs4 (BeautifulSoup)

I'm working in Python and using Flask. When I run my main Python file on my computer, it works perfectly, but when I activate venv and run the Flask Python file in the terminal, it says that my main Python file has "No Module Named bs4." Any comments or advice is greatly appreciated.

Activate the virtualenv, and then install BeautifulSoup4:

$ pip install beautifulsoup4

When you installed bs4 with easy_install, you installed it system-wide. So your system python can import it, but not your virtualenv python. If you do not need bs4 to be installed in your system python path, uninstall it and keep it in your virtualenv.

After reading all the answers, what worked for me was adding the --clean option with pyinstaller.

Example:

pyinstaller --onefile --console --clean --name Email_Parser main.py

What I tried and did not work:

Deleting and recreating the virtual environment
python -m pyinstaller
Installing pyinstaller in the virtual environment

In my case, the when do

pip install beautifullsoap4

always gets installed to my python3.9 package where my

python3 --version

gave the output as Python 3.10.6 I fixed the issue of pip3 install by upgrading the pip and pointing correctly to 3.10 instead of 3.9

Then everything worked as expected

You will need to have pip in your PATH environment variable. If you don't have it then use this link: python -m pip install beautifulsoup4

This worked for me. Hopefully, it works for you too.

I also experienced this problem with Python 3. In my case I was able to solve it by running:

$ pip3 install BeautifulSoup4

Instead of:

$ pip install BeautifulSoup4

One more solution for PyCharm:

Go to File -> Settings -> Python Interpreter, click on plus sign and find beautifulsoup4.

Click install.

The better method is ("-U" : Upgrade all package(s) to the newest available version.) :

$ python3 -m pip install -U pip && python3 -m pip install -U bs4

or install from apt (Debian, Ubuntu, Mint, etc.) :

$ sudo apt install python3-bs4

It is so annoying to find the answer has nothing to do with BeautifulSoup. To the linux users, be vary of running the command 'python', version 2 exits and you may have forgotten to change the bash file alias of python. And so you might have created the virtual environment using 3 with

python3 -m venv .venv

So, to install things, go with

python3 -m pip install beautifulsoup4

not

pip install beautifulsoup4

Things get installed in different versions and you scratch your head as to what is going on.

I have been searching far and wide in the internet.

I'm using Python 3.6 and MacOS. I have uninstalled and installed with pip3 install bs4 but that didn't work. It seems like python is not able to detect or search the bs4 module.

This is what worked: python3 -m pip install bs4

The -m option allows you to add a module name.

Addendum to the original query: modules.py

help('modules')

$python modules.py

It lists that module bs4 already been installed.

_codecs_kr          blinker             json                six
_codecs_tw          brotli              kaitaistruct        smtpd
_collections        bs4                 keyword             smtplib
_collections_abc    builtins            ldap3               sndhdr
_compat_pickle      bz2                 lib2to3             socket

Proper solution is:

pip install --upgrade bs4

Should solve the problem.

Not only that, it will show same error for other modules as well. So you got to issue the pip command same way as above for those errored module(s).

I did what @rayid-ali said, except I'm on a Windows 10 machine so I left out the sudo. That is, I did the following:

python3 -m pip install bs4

and it worked like a pycharm. Worked like a charm anyway.

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.

You might want to try install bs4 with

pip install --ignore-installed BeautifulSoup4

if the methods above didn't work for you.

A lot of tutorials/references were written for Python 2 and tell you to use pip install somename. If you're using Python 3 you want to change that to pip3 install somename.
