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.

For more information about virtualenvs, read this

For python2.x:

sudo pip install BeautifulSoup4 

For python3:

sudo apt-get install python3-bs4 

Just tagging onto Balthazar's answer. Running

pip install BeautifulSoup4 

did not work for me. Instead use

pip install beautifulsoup4 

Try this:

sudo python3 -m pip install bs4 

pip3 install BeautifulSoup4 

Try this. It works for me. The reason is well explained here..

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.

If you are using Anaconda for package management, following should do:

conda install -c anaconda beautifulsoup4

I will advise you to uninstall the bs4 library by using this command:

pip uninstall bs4

and then install it using this command:

sudo apt-get install python3-bs4

I was facing the same problem in my Linux Ubuntu when I used the following command for installing bs4 library:

pip install bs4

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.

This worked for me.

pipenv pip install BeautifulSoup4

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 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.

pip install --user BeautifulSoup4

pip3.7 install bs4 

Try this. It works with python 3.7

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.

The easiest is using easy_install.

easy_install bs4 

It will work if pip fails.

You might want to try install bs4 with

pip install --ignore-installed BeautifulSoup4 

if the methods above didn't work for you.

Try reinstalling the module OR Try installing with beautiful soup with the below command

pip install --ignore-installed BeautifulSoup4 

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).

In case you are behind corporate proxy then try using following command

pip install --proxy= BeautifulSoup4

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 

One more solution for PyCharm:

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

Click install.
