How To Resolve ModuleNotFoundError: No Module Named ‘PyQt5’ In Python

If you get the error ModuleNotFoundError: No module named ‘PyQt5’ in Python and don’t know what to do, I have a few suggestions for installing the PyQt5 module for you. Read the article below.

What causes the ModuleNotFoundError: No module named ‘PyQt5’ in Python?

The ModuleNotFoundError: No module named ‘PyQt5’ error happens because you have not installed the ‘PyQt5’ module to use it or you installed the wrong environment. I will do the installation in a virtual environment.

How to solve this error?

Install library ‘PyQt5’ 

Install the ‘PyQt5’ module. You can use Python pip. But note that you need to specify the exact version of Python you are using.

Example:

If you don’t have pip installed here is the solution for you in Python 3:

python -m pip install PyQt5

If you use Python 3, use the pip3 statement as follows:

pip3 install PyQt5

If you use Python 2, use the following pip command:

pip install PyQt5

Install ‘PyQt5’ on operating systems

I would install ‘PyQt5’ according to your operating system.

Install ‘PyQt5’ on Windows using pip

Before installing ‘PyQt5’, you need to create a virtual environment. Using a virtual environment helps you avoid incompatibilities between packages and break the system if you install incompatible libraries with your operating system.

You can activate the virtual environment with the following command:

venv\Scripts\Activate.ps1

Then you can install the ‘PyQt5’ module with the following command:

python3 -m install PyQt5 

If you do not have pip installed, use the following command:

python3 -m pip install PyQt5

Install ‘PyQt5’ on Mac using pip

Make sure you have installed Python and pip. Just like on Windows operating systems, you also need a virtual environment. Just like on Windows operating systems, you also need your virtual environment. You can activate the virtual environment with the following command:

source venv/bin/activate

Install ‘PyQt5’ in the command prompt environment:

python3 -m pip install PyQt5

Install module ‘PyQt5’ by Anaconda

The most well-known open-source Python data science platform is called Anaconda. Install “PyQt5” after setting up Anaconda and a virtual environment.

To create an anaconda environment:

conda create -n pyqt python=3.8

Enable the project area you will see ‘PyQt5’ in parentheses next to the line prompt:

source activate pyqt

Finally, install ‘PyQt5’ with the command:

conda install -c anaconda pyqt

Import PyQt5 module

Once you have successfully installed the PyQt5 module, to use it, you need to import this module with the following syntax:

from PyQt5.QtWidgets import QApplication, QWidget  

You can import other variables included in the module, here I am taking an example to make it easier for you to imagine.
