I encountered a problem when installing
readability-lxml on MacOS
src/lxml/includes/etree_defs.h:14:10: fatal error: 'libxml/xmlversion.h' file not found #include "libxml/xmlversion.h" ^ 1 error generated.
The cause of the problem is that I just upgraded Xcode and did not install the
command line tools for Xcode
Install in Xcode:
Xcode -> Preferences... -> Locations
Install using the command line:
Successfully installed readability-lxml again!
