I am attempting to use pip to install lxml. I have Windows 11 and Python version python-3.10.2-amd64. I am using Visual Studio Code (VSC) as well. I realized I needed lxml from this error message in my VSC terminal:
Traceback (most recent call last):

% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you
requested: lxml. Do you need to install a parser library?
From there, I tried to install lxml by using the command in the VSC terminal:
pip install lxml
And I got this error message:

Using cached lxml-4.6.5.tar.gz (3.2 MB)
So I went to this website to download libmxl2 and libxslt: https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml. After downloading the lxml‑4.7.1‑cp310‑cp310‑win_amd64.whl version (since it matched my python version) I tried using the following command in the windows command prompt:
pip install lxml-4.7.1-cp310-cp310-win_amd64.whl
And I got this result:
lxml is already installed with the same version as the provided wheel.
Use --force-reinstall to force an installation of the wheel.
So then I did the same command but added the —force-reinstall and it said it successfully installed lxml-4.7.1. Then I went back to the VSC terminal, ran «pip install lxml» and got the same error message as I did before. So I tried the «pip install lxml-4.7.1-cp310-cp310-win_amd64.whl» command in the VSC terminal and got this error:
ERROR: lxml-4.7.1-cp310-cp310-win_amd64.whl is not a supported wheel on this platform.
Then I thought that I should try the win32 version since I have an Intel processor. So I run this command in the command prompt:
pip install lxml-4.7.1-cp310-cp310-win32.whl
And I get this error message:
ERROR: lxml-4.7.1-cp310-cp310-win32.whl is not a supported wheel on this platform.
So I’m at a loss. Any help is greatly appreciated!
This is the command I used to install lxml:
sudo pip install lxml
And I got the following message in the Cleaning Up stage:

The «ImportError: lxml not found, please install it» is an error message that occurs when trying to import the lxml library in Python, which means that the library is not installed on your system. Lxml is a powerful library used for processing XML and HTML in Python, and it is a requirement for many popular Python packages such as Scrapy and Beautiful Soup. In this article, we will provide you with a few methods to resolve the error and get lxml installed correctly.
Method 1: Installing lxml using pip
To fix the «ImportError: lxml not found, please install it» error in Python, you can use pip to install the lxml library. Here are the steps to install lxml using pip:
- Open the command prompt or terminal on your computer.
- Type the following command and press Enter to check if pip is installed:
- If pip is not installed, download and install it from the official website.
- Once pip is installed, type the following command and press Enter to install lxml:
- Wait for the installation to complete. You should see a success message once the installation is done.
Here is an example code that uses lxml library to parse an XML file:
from lxml import etree
xml_file = etree.parse('example.xml')
root = xml_file.getroot()
print(root.tag)In the above example, we first import the etree module from the lxml library. We then parse an XML file using the etree.parse() method and get the root element using the getroot() method. Finally, we print the tag name of the root element using the tag attribute.
Overall, installing lxml using pip is a simple and effective way to fix the «ImportError: lxml not found, please install it» error in Python.
Method 2: Installing lxml using conda
To install lxml using conda, follow these steps:
-
Open the terminal or command prompt and type the following command to create a new conda environment:
conda create --name lxml_env -
Activate the new environment by typing the following command:
-
Install lxml by typing the following command:
-
Verify that lxml is installed by typing the following command:
If there are no errors, then lxml is installed and ready to use.
Here’s an example of how to use lxml to parse an XML file:
from lxml import etree # Parse the XML file tree = etree.parse('example.xml') # Get the root element root = tree.getroot() # Print the tag name of the root element print(root.tag) # Print the text of the first child element print(root[0].text)This code will parse an XML file called «example.xml» and print out the tag name of the root element and the text of the first child element.
Overall, installing lxml using conda is a simple and straightforward process that can be done in just a few steps. Once installed, lxml provides powerful tools for working with XML files in Python.
Method 3: Installing lxml from source
If you encounter the ImportError: lxml not found error message, you can try installing lxml from source.
Here are the steps:
- Download the latest version of lxml from the official website:
$ wget https://pypi.python.org/packages/source/l/lxml/lxml-4.6.3.tar.gz
$ tar -xzvf lxml-4.6.3.tar.gz
$ cd lxml-4.6.3- Install the required dependencies:
$ sudo apt-get install libxml2 libxml2-dev libxslt1-dev python-dev- Build and install lxml:
$ python setup.py build
$ sudo python setup.py install- Verify the installation by running the following command:
$ python -c "import lxml; print(lxml.__version__)"You should see the version number of lxml installed without any error message.
That’s it! You have successfully installed lxml from source and fixed the ImportError: lxml not found error.
Method 4: Installing lxml on Windows using precompiled binaries
If you are encountering the ImportError: lxml not found, please install it error in Python, you can fix it by installing lxml on your Windows machine using precompiled binaries. Here are the steps to do so:
-
Download the precompiled binary for lxml from the Unofficial Windows Binaries for Python Extension Packages website. Make sure to download the version that corresponds to your Python version and your Windows architecture (32-bit or 64-bit).
-
Open a command prompt window and navigate to the directory where you downloaded the lxml binary.
-
Install the lxml binary using the
pipcommand. Here is an example command for installing lxml version 4.6.3 for Python 3.9 64-bit:pip install lxml-4.6.3-cp39-cp39-win_amd64.whl -
Once the installation is complete, you can test that lxml is installed correctly by running the following Python code:
import lxml print(lxml.__version__)If the output shows the version number of lxml, then the installation was successful.
That’s it! You should now be able to use lxml in your Python projects without encountering the ImportError message.
