Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?

This error message suggests that you are missing a required library for parsing XML with the lxml module. You may need to install a parser library such as libxml2 or lxml's own parser library.

To install the required library, you can use pip, the Python package manager. Open a terminal or command prompt and run the following command:

pip install lxml

If that doesn't work, you may need to install the parser library separately. For example, on Ubuntu or Debian-based systems, you can use the following command:

sudo apt-get install libxml2-dev libxslt-dev python-dev

Once you have installed the required library, you should be able to import and use lxml without encountering this error message.
