python 安装setuptools时报Compression requires the (missing) zlib module错误的解决方案

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  
    self.run_command(cmd)  
  File "/usr/local/lib/python2.7/distutils/dist.py", line 972, in run_command  
    cmd_obj.run()

    cmd_obj.run()  
  File "/opt/oracle/sor/install/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 236, in run  
    dry_run=self.dry_run, mode=self.gen_header())  
  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 

处理方式:

# 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
