可能会遇到的问题

ImportError: No module named Image

解决办法：安装Python Imaging Library(PIL)

1

sudo pip PIL

安装PIL出现：
— JPEG support not available

— 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：
(1) 删除已经安装的PIL

pip uninstall PIL




(2) 安装相关库

sudoapt-get installlibjpeg8 libjpeg62-dev libfreetype6 libfreetype6-dev

sudoln -s /usr/lib/x86_64-linux-gnu/libjpeg.so/usr/lib/

sudoln -s /usr/lib/x86_64-linux-gnu/libfreetype.so/usr/lib/

sudoln -s /usr/lib/x86_64-linux-gnu/libz.so/usr/lib/




(3) 重新安装PIL

sudopip PIL

终端出现：

— JPEG support available
— ZLIB (PNG/ZIP) support available
— FREETYPE2 support available

现在试试，已经ok了
