今天幫朋友做個python的小工具，發現系統上缺少ptyhon的支持庫，返回如下信息

ImportError: No module named PIL
然后就下載安裝,因為機器上也沒有python的管理工具pip，所以也一并安裝
1. 安裝pip

sudo easy_install pip

pip 安裝成功就可以直接安裝pil或者pillow

2. 通過命令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. 所以就安裝pillow

pip install --use-wheel Pillow

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

弄了會別的回來發現還沒有下載完，這叫一個慢呀，于是放棄
4. Git

通過git下載源碼地址https://github.com/python-imaging/Pillow

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

然后開始編譯安裝

4.1

python setup.py build_ext -i

編譯完之后會提示運行測試例子，并且發現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 因為JPEG support not available，運行python selftest.py報告錯誤

1 tests of 57 failed.

于是只好卸載pillow

可以通過pip命令來卸載

pip uninstall pillow 
sudo pip uninstall pillow

成功之后需要安裝libjpeg的支持

brew install libjpeg

安裝成功之后重新編譯pillow
