背景: 虚拟机CentOS下安装Python辅助工具 setuptools报错，错误信息大概如下：
Traceback (most recent call last):
File "setup.py", line 94, in <module>
scripts = scripts,
File "/usr/local/lib/python2.7/distutils/core.py", line 152, in setup
dist.run_commands()
File "/usr/local/lib/python2.7/distutils/dist.py", line 953, in run_commands

File "/opt/oracle/sor/install/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 527, in make_zipfile
z = zipfile.ZipFile(zip_filename, mode, compression=compression)
File "/usr/local/lib/python2.7/zipfile.py", line 681, in __init__
"Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module
出错原因：
提示的很清楚，缺少 zlib模块导致安装失败
解决方式:
# yum install zlib
# yum install zlib-devel
下载成功后，进入python2.7的目录，重新执行
#make
#make install
此时先前执行的 软连接仍旧生效
然后进入 setuptool目录，
[root@localhost setuptools-5.2]# pythonnew setup.py install 重新安装
基本这样就可以搞定。
