"Python.h: No such file or directory"

剛才在安裝lxml的時候，遇到了一個意外的問題

Building against libxml2/libxslt in the following directory: /usr/lib
src/lxml/lxml.etree.c:4:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1

只好去GOOGLE才發現原來要安裝 python-dev 就可以了

# sudo apt-get install python-dev

ps:我有安裝python2.7 python3.2 誰會知道還要安裝 python-dev 阿（翻桌）
