ubuntu上用python安装扩展包遇到的一些问题
python的easy_install工具非常棒，安装和卸载组件非常方便，安装过程如下：
wget -q http://peak.telecommunity.com/dist/ez_setup.py
执行上面的命令把ez_setup.py文件下载到当前的目录下
执行：
python ez_setup.py
下载对应的setuptools-xx.egg文件，没想到出现以下错误：
zipimport.ZipImportError: can’t decompress data; zlib not available
解决办法：
(1)先安装系统相应的依赖库文件
sudo apt-get install zlibc zlib1g-dev
(2)到python安装目录下执行
sudo ./configure
编辑Modules/Setup文件
vim Modules/Setup
找到下面这句，去掉注释
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
重新编译安装：
sudo make
sudo make -i install
python ez_setup.py
现在就可以用 sudo easy_install 命令安装其他组件了
但是在实际过程中，提示需要先执行下面的命令，那就按提示操作执行：
sudo apt-get -f install
sudo apt-get install zlibc zlib1g-dev
root@az-aacdb01:/opt# chmod +x ez_setup.py
root@az-aacdb01:/opt# python ez_setup.py
