How to install lxml on Windows
Question:
I’m trying to install lmxl on my Windows 8.1 laptop with Python 3.4 and failing miserably.
First off, I tried the simple and obvious solution: pip install lxml. However, this didn’t work. Here’s what it said:

So then I looked on this great and helpful thing called The Internet and a lot of people have the same error of needing libxml2 and libxlst. They recommend a guy called Christoph Gohlke’s page where he provides some sort of binary thingy for a bunch of packages. You can find it here (quicklink to the lxml part).
So after I gave up on trying to find libxml2 and libxslt for pip, I decided to go there, and found an absolute ton of downloads. I know I need a 64-bit one, but I have no idea which “cp” I need.
So an answer either giving me a solution on the pip method or the Gohlke index method would be great.
Answers:
First, following the comments, I downloaded the lxml-3.4.2-cp34-none-win_amd64.whl file and tried to open it with a pip install, but it just told me it wasn’t a valid wheel file on my system or something.
Then, I downloaded the win_32 file and it worked! Maybe it’s because I have an Intel processor and AMD64 is, unsurprisingly, only for AMD processors.
Or you can also go to Christoph’s Gohlke’s Python page and then download the right lxml file. (Generally since I use python 3.4 and I have a windows, I download the lxml-3.4.4-cp34-none-win32.whl)
Go to the folder it is in. Click in the background (so nothing is selected), then leftshift + rightclick at the same time and click on open command window. Then type
C:/Python34/Scripts/pip install "NAME OF THE FILE YOU JUST DOWNLOADED.whl"
In this case it would be C:/Python34/Scripts/pip install "lxml-3.4.4-cp34-none-win32.whl"
Now hit enter. This worked well for me, and after you type the quote you can also press tab and it should fill the right one for you.
These instructions are for Windows7 or Windows8 with Python3.4.
However, they should work for various versions as the releases of python and other respective prerequisites change/evolve:
- Install Python3.4:
- Download the last release of Python3.4 from the downloads page HERE
- Direct link for Win32 MSI installer -> HERE
- Simply run the MSI to install python. It will register itself in the registry, and appear in Add/REmove Programs.
- NOTE: my instructions that follow assume that you choose to install python to the default path of
C:python34 when asked during the Python Installation Wizard
- Add the
C:python33 and C:python34scripts folders to the system path by adding those directories to the PATH environment variable from the Control Panel > System > Advanced System Settings link (Advanced Tab) > Environmental Variables (Button).
- Install OpenSSL:
- Download Win32 OpenSSL page from HERE for your version of Windows and PC architecture
- Download Visual C++ 2008 redistributables for your version of Windows and PC architecture
- Download OpenSSL for your version of Windows and architecture (the regular version, not the light one)
- Add the
c:openssl-win32bin (or similar) directory to your PATH, the same way you added C:python34 and C:python34scripts above.
- Install Setuptools (
get-pip.py should install Setuptools for you), but, just in case…
- Download
ez_setup.py HERE and save it in C:python34scripts
- Run
C:python34scripts> python ez_setup.py
- Install PIP
- Download
get-pip.py from HERE and save it in C:python34scripts
- Run
C:python34scripts> python get-pip.py
- Install LXML
- Download
LXML 3.4.4 from HERE for your version of Windows and PC architecture
- Run the EXE file
I also meet this problem recently. pip can’t not work on .whl file. Instead of fixing this, i install it through .exe file. you can download it from here.Please choose the right version of your python. Hope this can help you.
Looks like today in 2018, lxml can be installed from PyPI:

I had this issue with a requirements file that listed lxml==4.2.1. However, I was able to fix the problem by updating this to lxml==4.2.5.
From the distributer’s website, the correct command is:
pip install lxml==3.4.4
Of course, update version number to match the latest version.
Reference: https://pypi.org/project/lxml/3.4.4/
Go to this page – https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
Download the libxml which is compatible with you machine.
For example, in my case, I have 64-bit intel processor with python 3.10 installed.
so , I have downloaded lxml‑4.6.3‑cp310‑cp310‑win_amd64.whl .
then run –
pip install "download_path/lxml-4.6.3-cp310-cp310-win_amd64.whl"

I also meet this problem recently. pip can’t not work on .whl file. Instead of fixing this, i install it through .exe file. you can download it from here.Please choose the right version of your python. Hope this can help you.
Looks like today in 2018, lxml can be installed from PyPI:
C:UsersAdministrator>"c:Program FilesPython37python.exe" -m pip install -U pip wheel setuptools

I had this issue with a requirements file that listed lxml==4.2.1. However, I was able to fix the problem by updating this to lxml==4.2.5.
From the distributer’s website, the correct command is:
pip install lxml==3.4.4
Of course, update version number to match the latest version.
Reference: https://pypi.org/project/lxml/3.4.4/
Go to this page – https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
Download the libxml which is compatible with you machine.
For example, in my case, I have 64-bit intel processor with python 3.10 installed.
so , I have downloaded lxml‑4.6.3‑cp310‑cp310‑win_amd64.whl .
then run –
pip install "download_path/lxml-4.6.3-cp310-cp310-win_amd64.whl"
