How to install python developer package?

I am trying to get mod_wsgi 3.3 to work. When I run make it is telling me that I am missing the Python developer package. How do I get and install the Python developer package?

The error I get is as follows:

mod_wsgi.c:135:20: error: Python.h: No such file or directory mod_wsgi.c:138:2: error: #error Sorry, Python developer package does not appear to be installed. mod_wsgi.c:142:2: error: #error Sorry, mod_wsgi requires at least Python 2.3.0 for Python 2.X. mod_wsgi.c:150:2: error: #error Sorry, mod_wsgi requires that Python supporting thread. mod_wsgi.c:153:21: error: compile.h: No such file or directory mod_wsgi.c:154:18: error: node.h: No such file or directory mod_wsgi.c:155:20: error: osdefs.h: No such file or directory

What is Python-dev package?

python-dev is the package that contains the header files for the Python C API, which is used by lxml because it includes Python C extensions for high performance.

yum install python-devel will work.

If yum doesn't work then use

apt-get install python-dev
