MacOSX安裝autopy時遇到錯誤

今天在安裝autopy模塊的時候遇到了無法安裝的問題

最初使用easy_install autopy來安裝，報錯如下：

error: Setup script exited with error: command 'cc' failed with exit status 1

查看src/screengrab.c發現是由於OpenGL沒有更新版本，存在一些已經被棄用的方法。解決辦法很簡單，增加的頭文件即可，如下(箭頭所指既爲所加頭文件)：

再次編譯報錯如下：

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

安裝libpng，下載地址

再次編譯OK，安裝成功！

PS：附安裝編譯安裝方法如下：

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

done！
