How to Fix ModuleNotFoundError (No Module Named) Error in Python

3 min readAug 3, 2022

When I was learning Python one of the first and most common errors I would run into was ModuleNotFoundError. Usually followed by no module named (and the name of the module that wasn’t installed.)

For visual speed learners, here’s a video.

How to solve ModuleNotFoundError (no module named) in Python

The ModuleNotFoundError: No module named error is raised when Python cannot find the module you’re trying to import. Basically all it means is that you need to install the module/package before it can be imported into your program (with import keyword.)

If you get the error ModuleNotFoundError: No module named you need to install the missing module.

Here’s how to do it:

Open the terminal and type sudo pip install module_name
Be sure to replace module_name with actual name of the module you’re trying to install.
2. Press Enter and type in your password (if prompted). This will install the missing Python module.

This can happen for a number of reasons, including incorrect module names, incorrect module paths, and unintended circular dependencies. In this tutorial, we’ll take a look at some of the most common causes of this error and how to fix them.

Module Doesn’t Exist (It Wasn’t Installed Yet)

One common cause of the “ModuleNotFoundError: No module named” error is simply that the module you’re trying to import doesn’t exist. This can happen if you’ve misspelled the module name, or if you’re trying to import a module that’s not in your Python path.

To fix this, make sure you’re using the correct module name, and that the module is in your Python path.

Circular Dependency

Another common cause of this error is a circular dependency. That is, two modules that are trying to import each other. This will cause an infinite loop, and eventually raise the “ModuleNotFoundError: No module named” error.

To fix this, make sure that there are no circular dependencies in your code. Finally, make sure that all modules are imported in the correct order. If one module imports another before it’s been fully initialized, this can also lead to the “ModuleNotFoundError: No module named” error.

Other Causes

There are many other causes of the “ModuleNotFoundError: No module named” error, but these are some of the most common. If you’re seeing this error in your own code, make sure to check for these potential causes and fix them accordingly. With a little troubleshooting, you should be able to get your code up and running in no time!
