Error when installing scrapy using pypi

Question

I'm on Debian 6 with python 2.7 and I've tried to install scrapy (according to the doc) using the command:

pip install Scrapy

and got this error

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c twisted/runner/portmap.c -o build/temp.linux-x86_64-2.7/twisted/runner/portmap.o

Cleaning up...
Command /usr/bin/python -c "import setuptools;__file__='/tmp/pip_build_root/Twisted/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-FSl8pj-record/install-record.txt --single-version-externally-managed failed with error code 1 in /tmp/pip_build_root/Twisted

I think the problem is when installing Twisted library, so i tried to install it alone using:

pip install Twisted

and got the same error.

How can I fix this ?

Answer 1

twisted/runner/portmap.c:10:20: error: Python.h: No such file or directory

Try installing python2.7-dev package.
