Installing lxml, libxml2, libxslt for Python 3. Asked 5 years, 2 months ago. Active 1 year, 7 months ago. Viewed 21k times. Building without Cython. Is libxml2 installed? It seems that this wheel file doesn't support either Windows 10 or Python 3.
Any help will be appreciated. Djidiouf Djidiouf 1 1 gold badge 10 10 silver badges 22 22 bronze badges. Did you try to download the file named for your python-version? MatsLindh sorry I tried the cp36 and previously the cp35 but only copy paste the later output, I edited my question. Good : Now you have to learn how to use lxml : Good luck. Show 14 more comments.

Simply putting the wheels in the Windows folder won't do anything? Python's module lxml needs them to run correctly. As this is one of the more recent posts or up-to-date on this topic. No pre-compiled binaries required. Add a comment. Matt Matt 1. Sign up or log in Sign up using Google. If the build fails, make sure they are installed. On MacOS-X, use the following to build the source distribution, and make sure you have a working Internet connection, as this will download libxml2 and libxslt in order to build them:.
Building from developer sources or from modified distribution sources requires Cython to translate the lxml sources into C code. The source distribution ships with pre-generated C source files, so you do not need Cython installed to build from release sources.
If you have read these instructions and still cannot manage to install lxml, you can check the archives of the mailing list to see if your problem is known or otherwise send a mail to the list. If you want to use lxml together with the official libxml2 Python bindings maybe because one of your dependencies uses it , you must build lxml statically. Otherwise, the two packages will interfere in places where the libxml2 library requires global configuration, which can have any kind of effect from disappearing functionality to crashes in either of the two.
To get a static build, either pass the --static-deps option to the setup. Most MS Windows systems lack the necessarily tools to build software, starting with a C compiler already. Microsoft leaves it to users to install and configure them, which is usually not trivial and means that distributors cannot rely on these dependencies being available on a given system.
In a way, you get what you've paid for and make others pay for it. Due to the additional lack of package management of this platform, it is best to link the library dependencies statically if you decide to build from sources, rather than using a binary installer. For that, lxml can use the binary distribution of libxml2 and libxslt , which it downloads automatically during the static build. It needs both libxml2 and libxslt, as well as iconv and zlib, which are available from the same download site.
Further build instructions are in the source build documentation. If you are not using macports or want to use a more recent lxml release, you have to build it yourself. While the pre-installed system libraries of libxml2 and libxslt are less outdated in recent MacOS-X versions than they used to be, so lxml should work with them out of the box, it is still recommended to use a static build with the most recent library versions.
Luckily, lxml's setup. Please read the MacOS-X build instructions. Like the tool? Help making it better! Your donation helps! Where to get it lxml is generally distributed through PyPI.
