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.

Method 1
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
Method 2
For python2.x:
sudo pip install BeautifulSoup4
For python3:
sudo apt-get install python3-bs4
Method 3
Just tagging onto Balthazar’s answer. Running
pip install BeautifulSoup4
did not work for me. Instead use
pip install beautifulsoup4
Method 4
Try this:
sudo python3 -m pip install bs4
Method 5
pip3 install BeautifulSoup4
Try this. It works for me. The reason is well explained here..
Method 6
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.

Method 7
If you are using Anaconda for package management, following should do:
conda install -c anaconda beautifulsoup4
Method 8
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
Method 9
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.
Method 10
This worked for me.
pipenv pip install BeautifulSoup4
Method 11
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.
Method 12
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.
Method 13
pip install --user BeautifulSoup4
Method 14
pip3.7 install bs4
Try this. It works with python 3.7
Method 15
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.
Method 16
The easiest is using easy_install.
easy_install bs4
It will work if pip fails.
Method 17
You might want to try install bs4 with
pip install --ignore-installed BeautifulSoup4
if the methods above didn’t work for you.
Method 18
Try reinstalling the module
OR
Try installing with beautiful soup with the below command
pip install --ignore-installed BeautifulSoup4
Method 19
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).
Method 20
In case you are behind corporate proxy then try using following command
pip install –proxy=http://www-YOUR_PROXY_URL.com:PROXY_PORT BeautifulSoup4
Method 21
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
Method 22
One more solution for PyCharm:
Go to File -> Settings -> Python Interpreter, click on plus sign and find beautifulsoup4.
Click install.
