ModuleNotFoundError: No module named ‘lxml’ in Python #

The Python «ModuleNotFoundError: No module named ‘lxml’» occurs when we forget to install the lxml module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install lxml command.

Open your terminal in your project’s root directory and install the lxml module.

If you are on Linux, you might have to install the build dependencies of lxml .

After you install the lxml package, try importing it like:

The Python error «ModuleNotFoundError: No module named ‘lxml’» occurs for multiple reasons:

  1. Not having the lxml package installed by running pip install lxml .
  2. Installing the package in a different Python version than the one you’re using.
  3. Installing the package globally and not in your virtual environment.
  4. Your IDE running an incorrect version of Python.
  5. Naming your module lxml.py which would shadow the official module.
  6. Declaring a variable named lxml which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

For example, my Python version is 3.10.4 , so I would install the lxml package with pip3.10 install lxml .

Notice that the version number corresponds to the version of pip I’m using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip :

If the «No module named ‘lxml’» error persists, try restarting your IDE and development server/script.

You can check if you have the lxml package installed by running the pip show lxml command.

The pip show lxml command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

For example, In VSCode, you can press CTRL + Shift + P or ( ⌘ + Shift + P on Mac) to open the command palette.

Then type «Python select interpreter» in the field.

Then select the correct python version from the dropdown menu.

If you are using a virtual environment, make sure you are installing lxml in your virtual environment and not globally.

You can try creating a virtual environment if you don’t already have one.

If the python3 -m venv venv command doesn’t work, try the following 2 commands:

  • python -m venv venv
  • py -m venv venv

Your virtual environment will use the version of Python that was used to create it.

You also shouldn’t be declaring a variable named lxml as that would also shadow the original module.

If the error is not resolved, try to uninstall the lxml package and then install it.

Try restarting your IDE and development server/script.

You can also try to upgrade the version of the lxml package.

This one is for using virtual environments (VENV) on Windows :

This one is for using virtual environments (VENV) on MacOS and Linux :

Conclusion #

The Python «ModuleNotFoundError: No module named ‘lxml’» occurs when we forget to install the lxml module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install lxml command.

How to Install lxml in Python?

The Python lxml library is among the top 100 Python libraries, with more than 22,913,226 downloads. This article will show you everything you need to get this installed in your Python environment.

Alternatively, you may use any of the following commands to install lxml , depending on your concrete environment. One is likely to work!

How to Install lxml on Windows?

  1. Type «cmd» in the search bar and hit Enter to open the command line.
  2. Type “ pip install lxml ” (without quotes) in the command line and hit Enter again. This installs lxml for your default Python installation.
  3. The previous command may not work if you have both Python versions 2 and 3 on your computer. In this case, try «pip3 install lxml» or “ python -m pip install lxml “.
  4. Wait for the installation to terminate successfully. It is now installed on your Windows machine.

Here’s how to open the command line on a (German) Windows machine:

First, try the following command to install lxml on your system:

Second, if this leads to an error message, try this command to install lxml on your system:

Third, if both do not work, use the following long-form command:

The difference between pip and pip3 is that pip3 is an updated version of pip for Python version 3. Depending on what’s first in the PATH variable, pip will refer to your Python 2 or Python 3 installation—and you cannot know which without checking the environment variables. To resolve this uncertainty, you can use pip3 , which will always refer to your default Python 3 installation.

How to Install lxml on Linux?

You can install lxml on Linux in four steps:

  1. Open your Linux terminal or shell
  2. Type “ pip install lxml ” (without quotes), hit Enter.
  3. If it doesn’t work, try «pip3 install lxml» or “ python -m pip install lxml “.
  4. Wait for the installation to terminate successfully.

The package is now installed on your Linux operating system.

How to Install lxml on macOS?

Similarly, you can install lxml on macOS in four steps:

  1. Open your macOS terminal.
  2. Type “ pip install lxml ” without quotes and hit Enter .
  3. If it doesn’t work, try «pip3 install lxml» or “ python -m pip install lxml “.
  4. Wait for the installation to terminate successfully.

The package is now installed on your macOS.

How to Install lxml in PyCharm?

Given a PyCharm project. How to install the lxml library in your project within a virtual environment or globally? Here’s a solution that always works:

  • Open File > Settings > Project from the PyCharm menu.
  • Select your current project.
  • Click the Python Interpreter tab within your project tab.
  • Click the small + symbol to add a new library to the project.
  • Now type in the library to be installed, in your example «lxml» without quotes, and click Install Package .
  • Wait for the installation to terminate and close all pop-ups.

Here’s the general package installation process as a short animated video—it works analogously for lxml if you type in “lxml” in the search field instead:

Make sure to select only “lxml” because there may be other packages that are not required but also contain the same term (false positives):

How to Install lxml in a Jupyter Notebook?

To install any package in a Jupyter notebook, you can prefix the !pip install my_package statement with the exclamation mark «!» . This works for the lxml library too:

This automatically installs the lxml library when the cell is first executed.

How to Resolve ModuleNotFoundError: No module named ‘lxml’?

Say you try to import the lxml package into your Python script without installing it first:

Because you haven’t installed the package, Python raises a ModuleNotFoundError: No module named ‘lxml’ .

To fix the error, install the lxml library using “ pip install lxml ” or “ pip3 install lxml ” in your operating system’s shell or terminal first.

See above for the different ways to install lxml in your environment.

How to Install lxml on Windows?

  1. Type "cmd" in the search bar and hit Enter to open the command line.
  2. Type “pip install lxml” (without quotes) in the command line and hit Enter again. This installs lxml for your default Python installation.
  3. The previous command may not work if you have both Python versions 2 and 3 on your computer. In this case, try "pip3 install lxml" or “python -m pip install lxml“.
  4. Wait for the installation to terminate successfully. It is now installed on your Windows machine.

Here’s how to open the command line on a (German) Windows machine:

Open CMD in Windows

First, try the following command to install lxml on your system:

pip install lxml

Second, if this leads to an error message, try this command to install lxml on your system:

pip3 install lxml

Third, if both do not work, use the following long-form command:

python -m pip install lxml

The difference between pip and pip3 is that pip3 is an updated version of pip for Python version 3. Depending on what’s first in the PATH variable, pip will refer to your Python 2 or Python 3 installation—and you cannot know which without checking the environment variables. To resolve this uncertainty, you can use pip3, which will always refer to your default Python 3 installation.

How to Install lxml on Linux?

You can install lxml on Linux in four steps:

Given a PyCharm project. How to install the lxml library in your project within a virtual environment or globally? Here’s a solution that always works:

  • Open File > Settings > Project from the PyCharm menu.
  • Select your current project.
  • Click the Python Interpreter tab within your project tab.
  • Click the small + symbol to add a new library to the project.
  • Now type in the library to be installed, in your example "lxml" without quotes, and click Install Package.
  • Wait for the installation to terminate and close all pop-ups.

Here’s the general package installation process as a short animated video—it works analogously for lxml if you type in “lxml” in the search field instead:

Make sure to select only “lxml” because there may be other packages that are not required but also contain the same term (false positives):
