背景: 虛擬機CentOS下安裝Python輔助工具 setuptools報錯，錯誤信息大概如下：
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

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
出錯原因：
提示的很清楚，缺少 zlib模塊導致安裝失敗
解決方式:
# yum install zlib
# yum install zlib-devel
下載成功後，進入python2.7的目錄，重新執行
#make
#make install
此時先前執行的 軟連接仍舊生效
然後進入 setuptool目錄，
[root@localhost setuptools-5.2]# pythonnew setup.py install 重新安裝
基本這樣就可以搞定。
