How to Fix Module Not Found Error: No module named '_ctypes' in Python

If you've tried to launch a Python file and encountered the frustrating error: ModuleNotFoundError: No module named '_ctypes', you're not alone. This issue typically arises on Fedora systems, particularly when using Python 3.10. Let’s take a deeper dive into the problem and outline clear steps you can take to resolve it.

Understanding the Problem

The error message is quite explicit. It indicates that the Python interpreter is unable to find the _ctypes module, which is a crucial part of the ctypes library. This library is used for calling functions in DLLs or shared libraries, allowing you to interface with C code directly from Python.

Common Causes of the Error

Missing Dependencies: The _ctypes module relies on the libffi library, which may not be installed on your system.

Python Environment Issues: If you're using a Python version manager like pyenv, there could be inconsistencies in your installed versions or environments.

Incomplete Python Installation: Sometimes, Python installations might not include certain modules due to missing underlying libraries during the installation process.

Solution Steps

To resolve the ModuleNotFoundError: No module named '_ctypes', follow these structured steps:

Step 1: Install Required Library

First, ensure that you have the necessary library installed on your system. Open your terminal and execute the following command:
