Modulenotfounderror: no module named setuptools_rust

In this article, we will discuss the solutions on how to solve the No Module Named setuptools_rust.

The No Module Named setuptools_rust error appears if the “setuptools” module is not perfectly installed on the system.

Genuinely, if we need to install the Python module within the source code, make sure to create it with a setup.py file.

Furthermore, setup.py is vulnerable to setuptools or disutils.

Usually, for the new upgrades of the Python module dependencies, it uses setuptools in the area of disutils.

Moreover, because of these reasons, when we execute the setuptools is not installed on the system and we execute the setup.py file we usually get an error.

How to solve the No Module Named setuptools_rust?

In Python language, the ” ImportError: No module named ‘setuptools_rust’ ” the error will appear because it cannot find the library package “setuptools_rust“.

The most usual cause of this error is that we have not installed the “setuptools-rust“. Decidedly with “pip install setuptools-rust“.

On the other hand, there is an error because we have various python versions in our computer. The setuptools_rust is not installed for the precise version we are using.

Steps to Fix the Error No Module Named setuptools_rust

Diagnostic checklist for “No module named ‘setuptools_rust'”

• Verify pip install target. Run pip show setuptools_rust — if not installed, run pip install setuptools_rust.
• Check the active Python interpreter. which python (mac/Linux) or where python (Windows). Both pip and python must point to the same environment.
• Check virtual environment activation. If you use venv/conda, activate before installing: source .venv/bin/activate.
• Rule out uppercase/lowercase. Python imports are case-sensitive: import PyPDF2 not import pypdf2.
• Rule out the pip-vs-package-name mismatch. Some packages install under a different name than you import (e.g. pip install beautifulsoup4 → import bs4).

Installing setuptools_rust

# Standard pip install
pip install setuptools_rust

# In a virtual environment (recommended)
python -m venv .venv
source .venv/bin/activate  # or .venv\Scripts\activate on Windows
pip install setuptools_rust

# With uv (faster alternative)
uv pip install setuptools_rust

Common causes for “No module named ‘setuptools_rust'”

• Python interpreter mismatch. Multiple Python installations can confuse pip. Verify with which python and which pip.
• Virtual environment not activated. If the venv isn’t activated, pip installs to your system Python instead.
• Notebook kernel mismatch. Jupyter uses a kernel that may differ from your terminal Python. Use %pip install setuptools_rust inside the notebook.
• Import name differs from install name. pip install beautifulsoup4 → import bs4. Check the package’s PyPI page.
• Windows PATH issues. Ensure Python is on PATH; use python -m pip install to invoke pip via the correct Python.

Working code example

# Verify install worked
import setuptools_rust
print(getattr(setuptools_rust, '__version__', 'no version attribute'))

Best practices

• Always use a virtual environment. Avoids most module-not-found errors.
• Use pip freeze to lock versions. pip freeze > requirements.txt makes your setup reproducible.
• Consider uv or Poetry. Modern package managers with better dep resolution and reproducibility.

Conclusion

To conclude, in this article we already provided the solutions to the error Modulenotfounderror: No Module Named setuptools_rust for windows, Linux, and MacOS.
