我正在尝试按照 debian 上的说明安装 PIL，但不知道如何修复此位：
我得到 --- build_ext 上提供 ZLIB (PNG/ZIP) 支持*自测试时未安装 ZLIB (PNG/ZIP) 支持
我缺少什么？
root@portman:~/dist/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 2.7.2+ (default, Dec 1 2011, 01:55:02)
[GCC 4.6.2]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
--- FREETYPE2 support available
--- LITTLECMS support 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.
root@portman:~/dist/Imaging-1.1.7# python selftest.py
--------------------------------------------------------------------

答案1
PIL 已经打包在 Debianpython-imaging包中：apt-get install python-imaging。
如果您确实想手动安装它，您可能需要安装 zlib1g-dev 软件包。
