核心提示：这篇文章主要介绍了在MacOS下安装Python的Pillow库的教程,Pillow库用来对图片进行各种处理操作,需要的朋友可以参考下

今天帮朋友做个python的小工具，发现系统上缺少ptyhon的支持库，返回如下信息

ImportError: No module named PIL
然后就下载安装,因为机器上也没有python的管理工具pip，所以也一并安装
1. 安装pip

sudo easy_install pip

pip 安装成功就可以直接安装pil或者pillow

2. 通过命令pip install pil

pip install Pil

Downloading/unpacking Pil 
 Could not find any downloads that satisfy the requirement Pil 
 Some externally hosted files were ignored (use --allow-external Pil to allow). 
Cleaning up... 
No distributions at all found for Pil 
Storing debug log for failure in /Users/macbook/Library/Logs/pip.log

3. 所以就安装pillow

pip install --use-wheel Pillow

Downloading/unpacking Pillow 
 Downloading Pillow-2.4.0.zip (6.5MB): 5.0MB downloaded 
Cleaning up...

弄了会别的回来发现还没有下载完，这叫一个慢呀，于是放弃
4. Git

通过git下载源码地址https://github.com/python-imaging/Pillow

git clone https://github.com/python-imaging/Pillow.git

然后开始编译安装

4.1

python setup.py build_ext -i

编译完之后会提示运行测试例子，并且发现JPEG support not available

-------------------------------------------------------------------- 
version   Pillow 2.4.0 
platform   darwin 2.7.5 (default, Aug 25 2013, 00:04:04) 
       [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] 
-------------------------------------------------------------------- 
--- TKINTER support available 
*** JPEG support not available 
*** OPENJPEG (JPEG2000) support not available 
--- ZLIB (PNG/ZIP) support available 
*** LIBTIFF support not available 
--- FREETYPE2 support available 
*** LITTLECMS2 support not available 
*** WEBP support not available 
*** WEBPMUX support not available 
-------------------------------------------------------------------- 
To add a missing option, make sure you have the required 
library, and set the corresponding ROOT variable in the 
setup.py script. 
 
To check the build, run the selftest.py script.

4.2 因为JPEG support not available，运行python selftest.py报告错误

1 tests of 57 failed.

于是只好卸载pillow

可以通过pip命令来卸载

pip uninstall pillow 
sudo pip uninstall pillow

成功之后需要安装libjpeg的支持

brew install libjpeg

安装成功之后重新编译pillow
