Are you facing the ‘ModuleNotFoundError: No module named Cryptodome’ error while running your Python code?
If yes then…
This error can be frustrating, especially if you are new to Python programming.
But don’t worry, in this article, we will explain what this error means, what causes it, and most importantly, how to fix it.
Prior to that let’s briefly define…
What is modulenotfounderror ?
The modulenotfounderror occurs when you have not installed the module or the module has not been installed correctly.
To resolve the error, you must first determine whether it is installed.
You should also check the Python path on your system.
What is Cryptodome?
Cryptodome is a Python library that provides secure encryption and decryption algorithms.
It is a fork of the popular PyCrypto library and is used by many Python developers for cryptography-related tasks.
Modulenotfounderror: no module named ‘cryptodome’
There are several reasons why you might be facing Modulenotfounderror: no module named ‘cryptodome’.
Here are some of the most common causes:
- The Cryptodome library is not installed on your system.
- The version of the Cryptodome library you have installed is not compatible with your Python version.
- The path to the Cryptodome library is not set correctly.
How to solve Modulenotfounderror no module named cryptodome
Now that we have a good understanding of what causes this error, let’s explore how to fix it. Here are the steps you can take:
- Check the Python version
Before installing the pycryptodome in your system, check the python version you have first.
Use this command to check:
python –version
For python 2.xx use pip command, hence if you are using python 3.xx use pip3 command. - Check if Cryptodome is installed
The first thing you should do is check if the Cryptodome library is installed on your system.
You can do this by running the following command in your terminal:
pip list
This command will list all the Python libraries installed on your system.
Look for ‘Cryptodome‘ in the list. If you can’t find it, then you need to install it.
- Install Cryptodome
To install the Cryptodome library, you can use the following command:
pip3 install pycryptodomex
This command will install the latest version of Cryptodome on your system.
- Check if the Error is Resolved
Once you have installed Cryptodome, try running your Python code again.
If the error was caused by the missing Cryptodome library, it should be resolved now. - Another solution: pycryptodome installation using conda
Conda, like pip, allows us to install pycryptodome with a single command.
However, we must ensure that conda is installed on the system.
Wherein the Conda manager is included by default with the Anaconda distribution.
Since Anaconda is more focused on scientific library platforms that support Machine Learning, AI, advanced data analysis, and so on.
Conda is less common than pip due to the specification.
Anyways, Here is the command to install pycryptodome with conda.
conda install -c conda-forge pycryptodome
That’s it, I think we all covered what should we want to know regarding this error.
Frequently Asked Questions
Official documentation
What is Python ModuleNotFoundError and what causes it?
ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.
How do I fix ‘ModuleNotFoundError: No module named X’?
Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.
Why does my code work in one environment but not another?
Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.
Is ModuleNotFoundError the same as ImportError?
ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.
Where can I find more ModuleNotFoundError fixes?
Browse the ModuleNotFoundError reference hub for 198+ specific module fixes (TensorFlow, Flask, Django, pandas, numpy, etc.). For related issues see ImportError. For broader Python setup see Python Tutorial hub.
