可能会遇到的问题 ImportError: No module named Image解决办法:安装Python Imaging Library(PIL)
安装PIL出现: — ZLIB (PNG/ZIP) support not available — FREETYPE2 support not available 操作jpeg图片和png图片出现: IOError: decoder jpeg not available 和 IOError: encoder zip not available 解决办法:
(2) 安装相关库
(3) 重新安装PIL
终端出现: — JPEG support available 现在试试,已经ok了 |
