Cannot install Lxml on Mac os x 10.9

I want to install Lxml so I can then install Scrapy.

When I updated my Mac today it wouldn't let me reinstall lxml, I get the following error:

In file included from src/lxml/lxml.etree.c:314:
/private/tmp/pip_build_root/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found
#include "libxml/xmlversion.h"
^
1 error generated.
error: command 'cc' failed with exit status 1


I have tried using brew to install libxml2 and libxslt, both installed fine but I still cannot install lxml.

Last time I was installing I needed to enable the developer tools on Xcode but since its updated to Xcode 5 it doesnt give me that option anymore.

Does anyone know what I need to do?

Answer

you should install or upgrade command line tool for xcode. please try command in terminal:

xcode-select --install
