由於處理圖片需要用到PIL模塊，具體的安裝步驟如下：
1. 安裝PIL所需的系統庫
1 yum install zlib zlib-devel
2 yum install libjpeg libjpeg-level
3 yum install freetype freetype-devel
2. 使用PIP安裝PIL模塊
1 pip install PIL
3.安裝
1 python setup.py build_ext -i
2 running build_ext

16 To add a missing option, make sure you have the required
17 library, and set the corresponding ROOT variable in the
18 setup.py script.

20 To check the build, run the selftest.py script.
3.依然有兩個報錯,不過不影響使用
另外:安裝完成后提示以下錯誤：
- *** TKINTER support not installed
- *** JPEG support not installed
- *** ZLIB (PNG/ZIP) support not installed
- *** FREETYPE2 support not installed
- *** LITTLECMS support not installed
或下面的錯誤：
- IOError: decoder jpeg not available
可以用如下方案:
修改PIL的安裝配置文件，因此不能通過PIP安裝，而需要下載代碼包進行安裝：
- wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
- tar xvfz Imaging-1.1.7.tar.gz
- python setup.py build_ext -i
- 修改setup.py：
- TCL_ROOT = "/usr/lib64/"
- JPEG_ROOT = "/usr/lib64/"
- ZLIB_ROOT = "/usr/lib64/"
- TIFF_ROOT = "/usr/lib64/"
- FREETYPE_ROOT = "/usr/lib64/"
- LCMS_ROOT = "/usr/lib64/"
- python setup.py
默認TCL_ROOT的設置為NONE，因此傳到系統庫的路徑。python setup.py build_ext -i是用來進行安裝前的檢查。
按照以上步驟安裝正常了。
