无法在Windows上安装python lxml（和libxml2）

Question

I'm trying to install lxml on windows (pip install lxml) but i keep getting following error:

*****
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
****************************************************************************

Command "C:\Python34\python.exe -c "import setuptools, tokenize;__file__='C:\\Us
ers\\meme\\AppData\\Local\\Temp\\pip-build-m_doxfaj\\lxml\\setup.py';exec(comp
ile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __fi

-record\install-record.txt --single-version-externally-managed --compile" failed
 with error code 1 in C:\Users\meme\AppData\Local\Temp\pip-build-m_doxfaj\lxml

I've tried to download a binary files for windows from here ( ftp://ftp.zlatkovic.com/libxml/ ) and adding them to path but it doesn't seem to help.

Manual download lxml wheel( http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml for cp34) file also fails upon trying to install with the following error log:

I'm using python34 32bit on x64 win7 machine.

You can try the binary from here . First do pip install wheel and then pip install <filename.whl> to install the downloaded binary.
