Mac安裝PIL模塊

sudo easy_install -f http://www.pythonware.com/PRoducts/pil/ Imaging如果出現(xiàn)錯誤，則執(zhí)行命令xcode-select --install，然后重新進(jìn)行上一步，具體錯誤如下：
　　/applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/tk.h:78:11: fatal error: 
    　　  'X11/Xlib.h' file not found
　　#       include <X11/Xlib.h>
 
再安裝Pillow模塊即可：
sudo pip install -U Pillow測試抓取屏幕：
from PIL import ImageGrabdef grab_image(addr):    im = ImageGrab.grab()    im.save(addr,"jpeg")if __name__ == "__main__":    grab_image("test.jpeg")
