bobince和Luper帮助了.
确保安装这些软件包然后重新编译Python：
sudo aptitude install zlib1g-dev libreadline6-dev libdb4.8-dev libncurses5-dev

安装后,我尝试安装setuptools.py

$sh setuptools-0.6c11-py2.7.egg   
Traceback (most recent call last):  
  File "<string>",line 1,in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

然后我安装了zlib：

$sudo aptitude install zlibc

在重新编译Python之前：

但是setuptools仍然不会安装：

$sh setuptools-0.6c11-py2.7.egg   
Traceback (most recent call last):  
  File "<string>",in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

我很困惑

我检查了我的权限：

lrwxrwxrwx 1 root      18 Oct 28 18:19 /usr/bin/python -> /usr/bin/python2.7
lrwxrwxrwx 1 root      24 Oct 28 18:26 /usr/bin/python2.7 -> /usr/local/bin/python2.7
lrwxrwxrwx 1 root       9 Oct 28 15:13 /usr/bin/python2 -> python2.6
-rwxr-xr-x 1 root 2613296 Apr 16  2010 /usr/bin/python2.6

我注意到我添加了一个额外的步骤,所以我重构了它：

llrwxrwxrwx 1 root      24 Oct 28 18:33 /usr/bin/python -> /usr/local/bin/python2.7  
lrwxrwxrwx 1 root       9 Oct 28 15:13 /usr/bin/python2 -> python2.6  
-rwxr-xr-x 1 root 2613296 Apr 16  2010 /usr/bin/python2.6

所以现在,Python2.7应该是默认的版本,但它仍然失败.

$sh setuptools-0.6c11-py2.7.egg --prefix=/usr/local/bin/python2.7  
Traceback (most recent call last):  
  File "<string>",in <module>  
zipimport.ZipImportError: can't decompress data; zlib not available

zlib应该在哪里找到正确的工作？

$find / -name zlib 2>/dev/null  
/home/username/sources/Python-2.7/Modules/zlib  
/home/username/sources/Python-2.7/Demo/zlib
