1. Python Errors

modulenotfounderror no module named ‘webcolors’

webcolors is a module for working with HTML/CSS color definitions.

Support is included for normalizing and converting between the following formats (RGB colorspace only; conversion to/from HSL can be handled by the colorsys module in the Python standard library):

  • Specification-defined color names
  • Six-digit hexadecimal
  • Three-digit hexadecimal
  • Integer rgb() triplet
  • Percentage rgb() triplet

The Python ModuleNotFoundError: No module named ‘webcolors’ occurs when we forget to install the webcolors module before importing it or installed it in an incorrect environment. To solve the error, install the module by running the pip install webcolors command.

how to fix modulenotfounderror no module named webcolors

Open your terminal in your project’s root directory and install the webcolors module.

# 👇️ in a virtual environment or using Python 2
pip install webcolors

# 👇️ for python 3 (could also be pip3.10 depending on your version)
pip3 install webcolors

# 👇️ if you get permissions error
sudo pip3 install webcolors

# 👇️ if you don’t have pip in your PATH environment variable
python -m pip install webcolors

# 👇️ for python 3 (could also be pip3.10 depending on your version)
python3 -m pip install webcolors

# 👇️ for Anaconda
conda install -c conda-forge webcolors

The Python error “ModuleNotFoundError: No module named webcolors” occurs for multiple reasons:

  1. Not having the webcolors package installed by running pip install webcolors.
  2. Installing the package in a different Python version than the one you’re using.
  3. Installing the package globally and not in your virtual environment.
  4. Your IDE running an incorrect version of Python.
  5. Naming your module webcolors.py which would shadow the official module.
  6. Declaring a variable named webcolors which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

# 👇️ Checking version of python
python –version

For example, my Python version is 3.10.4

So I would install the webcolors package with pip3.10 install webcolors

pip3.10 install webcolors

# 👇️ if you get permissions error use pip3 (NOT pip3.X)
sudo pip3 install webcolors

Notice that the version number corresponds to the version of pip I’m using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip.

# 👇️ make sure to use your version of Python, e.g. 3.10
python3 -m pip install webcolors

If the “No module named webcolors” error persists, try restarting your IDE and development server / script.

You can check if you have the webcolors package installed by running the pip show webcolors command.

# 👇️ check if you have webcolors installed
pip3 show webcolors

# 👇️ if you don’t have pip setup in PATH
python3 -m pip show webcolors

The pip show webcolors command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

If you are using a virtual environment, make sure you are installing webcolors in your virtual environment and not globally.

You can try creating a virtual environment if you don’t already have one.

# 👇️ use correct version of Python when creating VENV
python3 -m venv venv

# 👇️ activate on Unix or MacOS
source venv/bin/activate

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ install webcolors in virtual environment
pip install webcolors

Your virtual environment will use the version of Python that was used to create it.

If the error persists, make sure you haven’t named a module in your project as webcolors.py because that would shadow the original webcolors module.

You also shouldn’t be declaring a variable named webcolors as that would also shadow the original module.

If the error is not resolved, try to uninstall the webcolors package and then install it.

# 👇️ check if you have webcolors installed
pip3 show webcolors

# 👇️ if you don’t have pip set up in PATH
python3 -m pip show webcolors

# 👇️ uninstall webcolors
pip3 uninstall webcolors

# 👇️ if you don’t have pip set up in PATH
python3 -m pip uninstall webcolors

# 👇️ install webcolors
pip3 install webcolors

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install webcolors

Try restarting your IDE and development server/script.

You can also try to upgrade the version of the webcolors package.

pip3 install webcolors –upgrade

# 👇️ if you don’t have pip set up in PATH
python3 -m pip install webcolors –upgrade

Conclusion

The Python “ModuleNotFoundError: No module named webcolors” occurs when we forget to install the webcolors module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install webcolors command.
