python下的setuptools带有一个easy\_install的工具，  
在安装python的每三方模块、工具时很有用，也很方便。  
安装setuptools前先安装pip，  
请参见《python下pip的安装》  
  
1. 下载:  
在它的官网可以下载到安装包:  
https://pypi.python.org/pypi/setuptools  
  
页面最下面的是它的安装链接,如:  
$wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz\#md5=f07e4b0f4c1c9368fcd980d888b29a65   
  
2. 安装  
$ tar -zxvf setuptools-12.0.3.tar.gz  
$ cd setuptools=12.0.3  
$ python setup.py install  
  
3. 出现错误提示:

No local packages or download links found for meld3>=1.0.0

解决办法:  
上网查询了问题原因： 是curl的证书太老了需要下载最新的证书：  
下载最新的证书文件 、    
$ wget http://curl.haxx.se/ca/cacert.pem    
更名为ca-bundle.crt放置到默认目录    
$ mv cacert.pem ca-bundle.crt   
$ mv ca-bundle.crt /etc/pki/tls/certs
