For a while now i have been trying to figure out how to install lxml but have had no such luck. As a last ditch of hope. I've come here for some solutions or clarification. So far I've already tried nearly all the ways told before in other answer threads but have had no luck.
Firstly I've tried the following:
pip install lxml
pip3 install lxml
python -m pip install lxml
Which threw an error...
ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n"
** make sure the development packages of libxml2 and libxslt are installed **
C:\Users\Me\AppData\Local\Temp\xmlXPathInit1owazwq3.c(1): fatal error C1083: Cannot open include file: 'libxml/xpath.h': No such file or directory

Failed building wheel for lxml
I then went on and tried to install wheel...
python -m pip install wheel
C:\Users\Me>python -m pip install wheel
Requirement already satisfied (use --upgrade to upgrade): wheel in c:\python35\lib\site-packages
Which seems to have worked.
However when i tried to install lxml again...
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\cl.exe' failed with exit status 2

i then tried downloading the .whl files..
python -m pip install lxml-3.6.0-cp35-cp35m-win_amd64.whl
^Downloaded nearly all of these .whl files
only to come to the same conclusion each and every
lxml-3.6.0-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
Sadly none of these have been able to install lxml...
Is lxml able to run on python3.5.1?
Any help at all will be helpful :)
Check what version you need to download with...
import sys
is_64bits = sys.maxsize > 2**32
print(is_64bits )
Then download the right version of lxml.. http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

Installing numba and llvmlite Python on Windows 10 failure
I have tried to install Python numba on Windows 10 using
pip install numba
with partial success, but a failure installing llvmlite

Doesn't know where LLVM is installed?
So I used Windows Environment editor to add LLVM_DIR with value C:\Program Files\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0.0-r4\mingw64\lib\cmake\llvm
in the hope that it will use one of the four Clang versions that I have installed at C:\LLVM\clang-1100, C:\LLVM\clang-1000 ...
latest binary is C:\LLVM\clang-1100\LLVM\bin
I also have VS 1017 and 1019 installed, and all compilers are working OK from other IDEs and builds.
and downloaded the most recent wheel
llvmlite-0.34.0-cp39-cp39-win_amd64.whl
and added LLVM_DIR to system PATH
C:\Program Files\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0.0-r4\mingw64\lib\cmake\llvm

This suggests that the output folder location is not specified, or that VS incremental build option is not set to 'not used'.
Or that I should use an LLVM version, but I don't know how to specify which one, and not use VS2017.
Suggestions how to get out of this rabbit hole most welcome ;-)

I wanted to install librosa but I get stack with this error, but I managed to solve it with this:
first I download the last version of llvmlite Here
than I run the following command:
pip install llvmlite-0.35.0-cp39-cp39-win_amd64.whl
next for all packages need by librosa I install them as follow:
pip install --no-deps packageName
or just for more sample do as follow :
pip install librosa --ignore-installed llvmlite
I first try to run the basic pip install command for it:
C:\Program Files (x86)\Python35-32>pip install lxml

I also tried to build lxml from sources ( https://github.com/lxml/lxml ) but it needs the libxml2 dependencies as well.
I tried to install it with wheel as well after downloading the lxml file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml :
C:\Program Files (x86)\Python35-32>pip install C:\Users\Djidiouf\Downloads\lxml-3.6.4-cp35-cp35m-win_amd64.whl
lxml-3.6.4-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
It seems that this wheel file doesn't support either Windows 10 or Python 3.5.
Any help will be appreciated.
lxml uses libxml2, libxslt (in background) but libxml2, libxslt are not Python modules - it's C/C++ libraries. So you can't install them using pip. You have to download and install them manually.
You can find precompiled lxml for Windows on Unofficial Windows Binaries for Python Extension Packages
cp35 in file name means version for Python 3.5.
win32 in file name means version for 32bit Python.
amd64 in file name means version for 64bit Python.
You probably use 32bit Python because I see 32 and (x86) in your path
C:\program files (x86)\python35-32\python.exe
You should find links to libxml2, libxslt on this page too. This libraries has .dll and .exe files and you can put them in any folder which is in PATH variable. Libraries mostly are installed in C:\Windows or in subfolder.
libxml2, libxslt may have also C/C++ header files *.h which you may need when you compile lxml. (on Linux this files are in separated packages
libxml2-dev, libxslt-dev)
BTW: You can use Anaconda distribution (instead of Python.org distribution). It installs the same Python but with some precompiled modules - ie. it installs lxml automatically. Anaconda can be the best solution for Windows users.
List of all modules: https://docs.continuum.io/anaconda/pkg-docs
Also, check your pip --version. I had v19.0 and Gohlke .whl binaries would not install. Upgrade to 19.2 or greater.

In my system when I type make:

'make' is not recognized as an internal or external command,

So, clearly make is missing. But I installed make using conda:

So I have mingw 4.7 already installed.
How could I remove the error and get the package?
Many thanks for the help.
make is not in your PATH.
Do echo %PATH% and check if the path to your msys utilities is in there. Otherwise you can edit this variable by following the instructions here: Adding directory to PATH Environment Variable in Windows

I tried it in an environment missing compiler paths and observed something similar. I think it's a problem in setuptools error handling when it doesn't find what it's expecting. The easiest way I've found is to use the VS Command Prompt shortcut installed with Visual Studio:
Perhaps the easiest way to do this is to run the build/install from a Visual Studio Command Prompt (a shortcut installed with Visual Studio that sources the appropriate environment and presents a shell).

So, I have going over this back and forth, I tried several of the solutions on this forum, none worked.
I have pip3 installed, Python 3.4, Visual Studio 2015 on Windows 10.
Now whenever I run the installing for a new module manually or through pip3 I get the following error:
Say I use the cmdline as such:
pip3 install numpy
I get :

Please help, considering to just use linux with python... less issues
This is based on #Jim answers in the comment section, basically make sure that you have the C++ compiler and windows SDK installed!
My problem was that when I installed Visual Studio, I did not select the windows SDK.
