Hi All,

 

I get the following errors when trying to install on OSX:

 

In file included from src/lxml/lxml.etree.c:320:
    src/lxml/includes/etree_defs.h:14:10: fatal error: 'libxml/xmlversion.h' file not found

any hints?

Hi Jack,

 

Firstly we'd highly recommend using Anaconda python rather than standard python on Mac OS X. Anaconda comes with many packages pre-installed, like lxml which appears to be the package you're having trouble with here.

 

That said, as the error message suggests, installing xcode from the apple store then running "xcode-select --install" from a terminal window should help ensure the required libraries are installed.

Thanks Dave,

updating xcode fixed the problem - must have forgotten to do it when moving to El Capitan.
