安装 setuptools 的时候，报如下错误：
creating 'dist/setuptools-0.6c11-py2.7.egg' and adding 'build/bdist.linux-x86_64/egg' to it
Traceback (most recent call last):

yum install zlib
yum install zlib-devel
安装完成后，重新编译 python2.7
不需要删除，只需要重新编译只需要make && make installl 安装就行了
然后重新安装setuptools：
cd setuptools-0.6c11
python setup.py install
