MacOSX安装autopy时遇到错误

今天在安装autopy模块的时候遇到了无法安装的问题

最初使用easy_install autopy来安装，报错如下：

查看src/screengrab.c发现是由于OpenGL没有更新版本，存在一些已经被弃用的方法。解决办法很简单，增加的头文件即可，如下(箭头所指既为所加头文件)：

再次编译报错如下：

src/png_io.c:3:10: fatal error: 'png.h' file not found#include <png.h>         ^1 error generated.error: command 'cc' failed with exit status 1

安装libpng，下载地址

再次编译OK，安装成功！

PS：附安装编译安装方法如下：

$ git clone git://github.com/msanders/autopy.git$ cd autopy$ python setup.py build# python setup.py install

done！
