How to Resolve the No Module Named PyPDF2 Error in Python

Encountering the infamous No Module Named PyPDF2 error in Python can be frustrating, especially when you are in the midst of an important project. This guide aims to provide a comprehensive guide to troubleshooting and resolving this common issue, whether you are using Jupyter Notebook, Spyder, or working on macOS.

Understanding the Error

The No Module Named PyPDF2 error arises when Python cannot locate the PyPDF2 library within your environment. This can occur due to various reasons such as incorrect installation, environment conflicts, or missing dependencies.

Common Scenarios

In Jupyter Notebook

When you see ModuleNotFoundError: No Module Named 'PyPDF2' in Jupyter Notebook, it usually means that the PyPDF2 library is not installed in the kernel being used. Even if you have PyPDF2 installed on your system, Jupyter's kernel may not have access to it.

In Spyder

Similar to Jupyter Notebook, Spyder uses a different interpreter or environment than your regular Python environment. The error ModuleNotFoundError: No Module Named 'PyPDF2' in Spyder usually points to a missing installation in Spyder’s environment.

On macOS

Mac users might face No Module Named 'PyPDF2' due to different Python versions being used. macOS comes with a pre-installed version of Python, which might not be the one you actively use.
