Modulenotfounderror: no module named _lzma [Solved]

In this tutorial, we will explore what is Modulenotfounderror: no module named _lzma, what causes this error and how to fix it.

Along with we’ll also provide some helpful tips and tricks for fixing this problem.

But before moving on to what we mentioned above we are going to briefly define what _lzma module is.

What is ‘_lzma’ module?

Basically, the _lzma module is a built-in Python module which provides a way to compress and decompress data using the LZMA compression algorithm.

In addition, this algorithm is a lossless data compression that achieved high compression ratios.

Moreover, it makes more useful for storing and transmitting large amounts of data efficiently.

The ‘_lzma‘ module is part of the Python Standard Library and is included in all Python installations by default.

What is Modulenotfounderror: no module named _lzma error ?

The Modulenotfounderror: no module named ‘_lzma’ error message is a common error that occurs when you’re trying to run Python code that requires the “_lzma” module, but Python can’t find it.

Wherein it’s already, the “_lzma” module is a built-in module in Python’s standard library that provides support for the LZMA compression algorithm.

Possible causes of no module named ‘_lzma’

This no module named ‘_lzma‘ error message can occur for several reasons, including:

  • The _lzma module is not installed on your system.
  • Your Python installation is corrupted or incomplete.
  • The path to the _lzma module is not set correctly.
  • There is a typo or error in your code that is preventing Python from finding the _lzma module.

Regardless of the cause, the Modulenotfounderror: no module named ‘_lzma error message means that your Python code cannot proceed until the issue is resolved.

How to solve Modulenotfounderror: no module named ‘_lzma’?

Now that we were already done exploring what Modulenotfounderror: no module named _lzma.

Thus possible causes of why this error occurs, now we will walk through possible solutions to fix it.

  1. Install the _lzma module.

    If the _lzma module is not installed in your system, the modulenotfounderror: no module named ‘_lzma’ will raise.

    So the first step to resolve this is to install it using pip of python package installer.

    pip install backports.lzma

    This command will download and install the “_lzma” module and any required dependencies.

  2. Upgrade python version

    If you are using an older version of Python, you may need to upgrade it to a newer version that supports the ‘_lzma‘ module.

    You can download the latest version of Python from the official website and install it on your system.

    python version

  3. Verify path

    Make sure that the path to the ‘_lzma’ module is correct.

    You can do this by running the following command in your Python environment:

    import _lzma

    If there are no errors, it means that the path is correct.

Additional Helpful Tips

Another helpful tip solution in fixing this error is finding the missing system dependencies and recompiling the dependencies.

Installing Python in pyenv, for example, entails removing the incorrect installation, installing the dependencies listed above, and reinstalling or recompiling Python.

As a side note, I believe this is one of the reasons Conda has grown in popularity.

It is because it ships many (binary) dependencies, problems like this one are avoided.

It should also be noted that Python’s ability to create simple interfaces for primarily C/C++ libraries is a strength that gives it a wide range of applications.

Then one of the reasons it has become so popular in Data Science and Machine Learning.


In summary, ModuleNotFoundError: No module named ‘_lzma’ error message can be a frustrating issue to deal with, but with the right troubleshooting steps, you can resolve it and get your website back up and running smoothly.

Remember to always keep your Python installation and modules up to date, and to check for missing dependencies if you encounter any issues.

That’s it we have provided solutions for fixing this error. However, if you follow the steps and encounter any further errors, feel free to ask for more help!
