在Mac OS系统上安装Python的Pillow库的好代码教程

每件事情都必须有一个期限,否则,大多数人都会有多少时间就花掉多少时间。积极的人在每一次忧患中都看到一个机会,而消极的人则在每个机会都看到某种忧患。

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 
Password: 
Uninstalling Pillow: 
 /Library/Python/2.7/site-packages/Pillow-2.4.0-py2.7-macosx-10.9-intel.egg 
 /usr/local/bin/pilconvert.py 
 /usr/local/bin/pildriver.py 
 /usr/local/bin/pilfile.py 
 /usr/local/bin/pilfont.py 
 /usr/local/bin/pilprint.py 
Proceed (y/n)? y
Successfully uninstalled 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

--------------------------------------------------------------------

*** LITTLECMS2 support not available 
*** WEBP support not available 
*** WEBPMUX support not available 
-------------------------------------------------------------------- 
python selftest.py

最后执行安装

sudo python setup.py install
