In Python, ModuleNotFoundError: No module named ‘urllib3’ error if we try to import the occurs ‘urllib3‘ module without installing the package or if you have not installed it in the correct environment.
In this tutorial, let’s look at installing the
urllib3 module correctly in different operating systems and solve ModuleNotFoundError: No module named ‘urllib3’ error.
What is ModuleNotFoundError: No module named ‘urllib3’?
There are various reasons why we get the ModuleNotFoundError: No module named ‘urllib3’ error
- Trying to use the module without installing the urllib3 package.
- If the IDE is set to the incorrect version of the Python/Python interpreter.
- You are using the virtual environment and the urllib3 module is not installed inside a virtual environment
- Installing the urllib3 package in a different version of Python than the one which is currently used.
- Declaring a variable name as the module name(urllib3)
If you are getting an error installing pip, checkout pip: command not found to resolve the issue.
How to fix ModuleNotFoundError: No module named ‘urllib3’?
urllib3 is not a built-in module (it doesn’t come with the default python installation) in Python; you need to install it explicitly using the pip installer and then use it.
urllib3 is a powerful, user-friendly HTTP client for Python. Much of the Python ecosystem already uses urllib3 and you should too. urllib3 brings many critical features that are missing from the Python standard libraries.
We can fix the error by installing the ‘urllib3‘ module by running the
pip install urllib3 command in your terminal/shell.
We can verify if the package is installed correctly by running the following command in the terminal/shell.
This will provide the details of the package installed, including the version number, license, and the path it is installed. If the module is not installed, you will get a warning message in the terminal stating WARNING: Package(s) not found: urllib3.
pip show urllib3
Name: urllib3 Version: 1.26.11 Summary: HTTP library with thread-safe connection pooling, file post, and more.

Solution 1 – Installing and using the urllib3 module in a proper way
Based on the Python version and the operating system you are running, run the relevant command to install the urllib3 module.
# If you are using Python 2 (Windows) pip install urllib3 # if you are using Python 3 (Windows) pip3 install urllib3 # If the pip is not set as environment varibale PATH python -m pip install urllib3 # If you are using Python 2 (Linux) sudo pip install urllib3 # if you are using Python 3 (Linux) sudo pip3 install urllib3 # In case if you have to easy_install sudo easy_install -U urllib3 # On Centos yum install urllib3 # On Ubuntu sudo apt-get install urllib3 # If you are installing it in Anaconda conda install -c conda-forge urllib3
Once you have installed the urllib3 module, we can now import it inside our code and use it as shown below.
import urllib3 http = urllib3.PoolManager() r = http.request("GET", "http://itsmycode.com/robots.txt") r.status print(r.data)

Solution 2 – Verify if the IDE is set to use the correct Python version
If you are still getting the same error even after installing the package, you can verify if the IDE you are using is configured with the correct version of the Python interpreter.
For Eg:- In the case of Visual Studio Code, we can set the Python version by pressing
CTRL + Shift + Por (
P on Mac) to open the command palette.
Once the command palette opens, select the Python interpreter and select the correct version of Python and also the virtual environment(if configured) as shown below.
Solution 3 – Installing urllib3 inside the virtual environment
Many different IDEs like Jupyter Notebook, Spyder, Anaconda, or PyCharm often install their own virtual environment of Python to keep things clean and separated from your global Python.
If you are using VS Code, then you can also create a virtual environment, as shown below.
In the case of virtual environments, you need to ensure that the urllib3 module needs to be installed inside the virtual environment and not globally.
Step 1: Create a Virtual Environment. If you have already created a virtual environment, then proceed to step 2.
Step 2: Activate the Virtual Environment
Step 3: Install the required module using the
pip install command
# Create a virtual Environment py -3 -m venv venv # Activate the virtual environment (windows command) venvScriptsactivate.bat # Activate the virtual environment (windows powershell) venvScriptsActivate.ps1 # Activate the virtual environment (Linux) source venv/bin/activate # Install urllib3 inside the virtual environment pip install urllib3
Solution 4 – Ensure that a module name is not declared name a variable name.
Last but not least, you may need to cross-check and ensure that you haven’t declared a variable with the same name as the module name.
You should check if you haven’t named any files as
urllib3.py as it may shadow the original urllib3 module.
If the issue is still not solved, you can try removing the package and installing it once again, restart the IDE, and check the paths to ensure that packages are installed in the correct environment path and Python version.
The ModuleNotFoundError: No module named ‘urllib3’ error when we try to import the occurs ‘urllib3‘ module without installing the package or if you have not installed it in the correct environment.
We can resolve the issue by installing the urllib3 module by running the
pip install urllib3 command. Also, ensure that the module is installed in the proper environment in case you use any virtual environments, and the Python version is appropriately set in the IDE that you are running the code.
