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:

  1. 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

    modulenotfounderror no module named cryptodome

    For python 2.xx use pip command, hence if you are using python 3.xx use pip3 command.

  2. 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.

    pip list

  3. 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.

    Install Cryptodome

  4. 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.

  5. 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.


In conclusion, we have provided solutions for fixing Modulenotfounderror: no module named cryptodome. If you follow these steps and encounter any further errors, feel free to ask for more help!
