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

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。

 

在ubuntu软件源里zlib和zlib-devel叫做zlib1g zlib1g.dev
        $ sudo apt-get install zlib1g
        $ sudo apt-get install zlib1g.dev
       直接输入上述命令后还是不能安装。这就要求我们先装ruby.
       在ubuntu里，zlib叫zlib1g，相应的zlib-devel叫zlib1g.dev。默认的安装源里没有zlib1g.dev。要在packages.ubuntu.com上找。
       $sudo apt-get install ruby
       然后再装zlib1g-dev就可以了
       $sudo apt-get install zlib1g-dev
