python easy_install工具安裝

    在安裝python第三方類庫時，python提供了一個類似於yum的命令easy_install，但是系統一般都是不會內建easy_install命令的，故將easy_install命令的安裝方法介紹如下：

   1）下載setuptools：

wget http://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c11-py2.4.egg#md5=bd639f9b0eac4c42497034dec2ec0c2b

   2）安裝setuptools

sh setuptools-0.6c11-py2.4.egg

   3）測試easy_install命令
