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 it's updated, to Xcode 5 it doesn't give me that option anymore.

Does anyone know what I need to do?

You should install or upgrade the command-line tool for Xcode. Try this in a terminal:

xcode-select --install
