1. 问题描述：运行python文件出现以下信息：
from PIL import ImageTk, Image
ImportError: No module named PIL
2. 解决方法：
(1) 安装python-imaging-tk
sudo apt-get install python-imaging-tk
(2) 安装Python Imaging Library(PIL):
PIL下载地址：http://www.pythonware.com/products/pil/
我目前下载的是Python Imaging Library 1.1.7 Source Kit, 包包名为 Imaging-1.1.7.tar.gz
解压：
tar -xzvf Imaging-1.1.7.tar.gz
切换到管理员命令行(ps:这里说明下， 为什么要切换到管理员身份呢？ 因为安装的时候要创建文件夹， 而普通用户身份是无法做到的， 如果不信你试下普通用户身份安装就知道了)：
sudo -s
以管理员身份安装：
python setup.py build
由上面可知JPEG、ZLIB、FREETYPE2、LITTLECMS还没安装， TKINTER库已安装.
Tkinter安装参照：http://blog.csdn.net/cryhelyxx/article/details/22514871
JPEG、ZLIB、FREETYPE2、LITTLECMS安装参照：http://blog.csdn.net/cryhelyxx/article/details/22589707
安装完 TKINTER、 JPEG、 ZLIB、FREETYPE2、LITTLECMS后， 再次检测：
python setup.py build
检测模块是否可用：
python setup.py build_ext -i
信息如下：
cryhelyxx@ada:~/下载/Imaging-1.1.7$ python setup.py build_ext -i
running build_ext

PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version 1.1.7
platform linux2 2.7.6 (default, Mar 30 2014, 00:48:22)
[GCC 4.6.3]
--------------------------------------------------------------------
--- TKINTER support available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
--- FREETYPE2 support available
*** LITTLECMS 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.
测试模块：
python selftest.py
信息如下：
cryhelyxx@ada:~/下载/Imaging-1.1.7$ python selftest.py
--------------------------------------------------------------------
PIL 1.1.7 TEST SUMMARY

1 items had failures:
1 of 57 in selftest.testimage
***Test Failed*** 1 failures.

cryhelyxx@ada:~/下载/Imaging-1.1.7$
显而易见， TKINTER、JPEG、 ZLIB、FREETYPE2都可用， LITTLECMS不可用， 但JPEG、ZLIB、LITTLECMS还是未成功安装， 有待研究...。
继续安装PIL:
python setup.py install
3. 检验是否成功安装python模块PIL:
终端输入：
python
from PIL import ImageTk, Image
如下：
4. OK, 没消息就是好消息， 恭喜你已成功安装python模块PIL...Enjoy it!!!
