PIL 安装

1.安装依赖包

1.1 ubuntu安装


apt-get install python-dev
apt-get install libjpeg-dev
apt-get install libjpeg8-dev
apt-get install libpng3 
apt-get install libfreetype6-dev
ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib
ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib 
ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib

或者

sudo apt-get build-dep python-imaging

由于ubuntu14中libfreetype 的头文件在/usr/include/freetype2目录下，但PIL中使用的路径是freetype，所以需要做以下操作

cd /usr/include
ln -s freetype2 freetype

1.2 redhat/centos

yum install python-devel libjpeg-turbo-devel libpng-devel freetype-devel

2.安装PIL

最后使用pip安装PIL pip install PIL --allow-unverified PIL --allow-all-external

安装完成后可以看到如下版本信息，可以看到PNG中支持JPEG/PNG/ZIP/FREETYPE2
