I am currently facing the problem that I would like to install the “lxml” library offline on a Windows computer. With an internet connection, it can be done using the command:

py -m pip install lxml

I have Python version 3.12.4 and pip version 24.0.

I have downloaded the library from “https://pypi.org” and then tried to manually install it using the command:

py -m pip install --no-index --find-links=C:UsersuserDownloads lxml

However, I receive the following error message:

**Processing c:usersuserDownloadslxml-5.2.2.tar.gz
Installing build dependencies … error

note: This error originates from a subprocess, and is likely not a problem with pip.

Accordingly, I tried to manually install the Cython package as well:

py -m pip install --no-index --find-links=C:UsersuserDownloads --no-build-isolation Cython

However, I encountered another error message during the installation:

Can someone help me with this? I have already installed Microsoft Visual C++ 14.0, but it still doesn’t work. Is there perhaps another way to install the lxml library? I found the following documentation (https://lxml.de/4.1/installation.html), but it looks more like a Linux guide to me, and it raises new questions.
