python 安装 setuptools Compression requires the (missing) zlib module 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

  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"


<strong>RuntimeError: Compression requires the (missing) zlib module
</strong>

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
