The Ultimate Guide to Installing PyJWT in Python IDEs and Platforms

How to Troubleshoot “ModuleNotFoundError: No module named ‘jwt'” in Python

As a Python developer, you’ve probably encountered the “ModuleNotFoundError: No module named ‘jwt'” error at some point. This error occurs when you try to run a Python script that requires the PyJWT module but the module is not installed on your system.

It’s a common error that can be frustrating, especially if you’re not sure where to begin with troubleshooting. In this article, we will cover some common causes of this error and provide some solutions to help you get back to coding!

Common Causes of the Error

The error “ModuleNotFoundError: No module named ‘jwt'” can be caused by several factors, including:

  • PyJWT not installed: PyJWT module is not installed on your system, or the necessary version is not installed.
  • Incorrect Python version: Some PyJWT versions may not be compatible with the specific version of Python you are using.
  • Working outside a virtual environment: You are working outside a virtual environment where the PyJWT module has been installed specifically for that environment.
  • IDE not configured correctly: The Integrated Development Environment (IDE) you are using is not set up correctly to recognize the PyJWT module.

Solution

We’ve identified the common causes of the error, so now let’s look at the possible solutions to resolve the issue.

1. Install PyJWT using pip

If you have not installed PyJWT on your system yet, installing it using pip would be the easiest solution. Follow these steps to install PyJWT using pip:

  1. Open a terminal window or command prompt and enter the following command: 
    pip install PyJWT
  2. This command will download and install the latest version of PyJWT on your system.

2. Check Python version compatibility

In some cases, PyJWT modules may not be compatible with the Python version you are using.

You can solve this by updating the Python version or installing a compatible version of the PyJWT module. Make sure to read installation instructions for correct and compatible versions for different Python versions.

3. Use a virtual environment

It’s a good practice to work within a virtual environment.

A virtual environment allows you to install specific dependencies, including PyJWT, for your project. Follow these steps to create and activate a virtual environment:

  1. Open a terminal or command prompt and navigate to the directory where you want to create the virtual environment.
  2. Enter the command python -m venv env_name (replace env_name with any name you want to give your virtual environment).
  3. Now, activate the virtual environment by running the command source env_name/bin/activate if you are on a Mac or Linux system, or env_nameScriptsactivate if you are running on Windows.
  4. Finally, install PyJWT within your virtual environment using the pip command – pip install PyJWT.

4. Import PyJWT module

After installing the PyJWT module, you need to import it into your Python code. In most cases, the error message occurs because PyJWT was never imported.

Importing the module ensures that your code can use it. Here is an example of how to import the PyJWT module in your Python script:

import jwt
# some code ...

Conclusion

In this article, we’ve discussed what causes the “ModuleNotFoundError: No module named ‘jwt'” error and provided some solutions to help solve this issue. We hope that this article has been helpful in getting you back to coding with PyJWT.

Remember always to work within virtual environments, install modules using pip, and always import the necessary modules into your Python code. Happy Coding!
