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


(3)重新执行

    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
