Troubleshooting Python: Fixing Setuptools and Setuptools_Rust ModuleNotFoundError

Troubleshooting Python: Fixing “ModuleNotFoundError” for

Setuptools and


Python is an incredibly powerful programming language that is widely used for web development, machine learning, and data analysis. It is open-source and has an extensive library of modules that allow developers to do more with less code.

However, even the most experienced developers can face issues in setting up their Python environment. One of the most common issues is the “ModuleNotFoundError.” In this article, we will explore a few solutions to fix this error for two modules:

Setuptools and



Setuptools is a widely-used package, which, among other things, helps in installing, building, and distributing Python packages. It is common to encounter the “ModuleNotFoundError: No module named ‘setuptools'” when trying to use

Setuptools, and there are a few ways to solve it.



The first and most straightforward solution is to install the

Setuptools module.

Setuptools can be installed via pip, which is a package installer for Python modules.

To install

Setuptools using pip, the following command will work:


!pip install setuptools




Another possible solution is to upgrade the

Setuptools module. If you already have

Setuptools installed but are still getting the error, it is possible that you have an older version of the module.

Upgrading the module might fix the error. To upgrade

Setuptools, run the following command:


!pip install –upgrade setuptools


Use Official Installer to Install


If the first two solutions do not work, there is a way to install

Setuptools directly from its official installer.

Download the appropriate version of the installer, depending on the operating system you’re using, from the official website and install it.

Create a Virtual Environment

If none of the above solutions works, creating a virtual environment can be another option. A virtual environment allows you to install the module within the environment, without affecting your system files.

To create a virtual environment:

1. Open the command prompt and navigate to the directory where you want to create the virtual environment.

2. Execute the following command:


python -m venv myvenv


This command creates a new virtual environment named “myvenv.”


Activate the virtual environment by running the following command:




4. Now, install the

Setuptools module using the pip command:


pip install setuptools


This should fix the “ModuleNotFoundError: No module named ‘setuptools'” error.


Setuptools_Rust is a Python library that allows us to use Rust libraries inside Python. Its installation can cause the “ModuleNotFoundError: No module named ‘setuptools_rust'” error.

However, this can easily be fixed by following the solutions mentioned below. Upgrade Pip and Install


To fix this error, the first solution is to upgrade pip and install the

Setuptools_Rust module. To do this, run the following command:


!pip install –upgrade pip setuptools_rust



Setuptools as well

Another solution is to install

Setuptools along with

Setuptools_Rust. Run the following command to install both modules.


!pip install setuptools setuptools_rust


Check If Package is Installed

It is possible that the package is already installed, but you’re still getting the error due to some misconfiguration. You can check whether the package is installed or not by running the following command in your terminal:


pip freeze | grep setuptools_rust


If this command returns any output, it means that the package is already installed.

Make Sure IDE is Using Correct Python Version

If you are using an IDE, you need to ensure that you are using the correct Python version. This might be the cause of the error.

You can check the version of Python you’re using in your IDE by going to the IDE settings or preferences.

Install Package in Virtual Environment

If none of the above solutions work, you can create a virtual environment and install the

Setuptools_Rust module inside the environment. The steps for creating a virtual environment are the same as mentioned above in the

Setuptools section, but instead of installing

Setuptools, install

Setuptools_Rust inside the virtual environment.

Wrapping Up

In conclusion, encountering an error like “ModuleNotFoundError: No module named ‘setuptools'” or “ModuleNotFoundError: No module named ‘setuptools_rust'” can be frustrating, but the solutions mentioned in this article can help you fix it quickly. Always make sure you’re using the latest version of pip and the respective modules, and if none of the solutions mentioned above work, try creating a virtual environment.

By following these steps, you can continue working on your Python project without any hindrance. In conclusion, the “ModuleNotFoundError” error is a common issue encountered by Python developers, especially when dealing with modules like

Setuptools and

Setuptools_Rust. However, with the solutions outlined in this article, you can easily fix this error and continue working on your Python project.

Always make sure to upgrade your modules, install them using pip or the official installer, check if they are installed, use the correct Python version in your IDE, or create a virtual environment. By following these steps, you can avoid confusion and frustration and ensure your Python environment is set up correctly.

Remember to keep these solutions in mind the next time you encounter the “ModuleNotFoundError” error and save yourself some valuable time.
