我一直在尝试用yum / python的urllib2来解决以下问题：
[root@...]# yum Traceback (most recent call last): File "/usr/bin/yum", line 4, in ? import yum File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 51, in ? import config File "/usr/lib/python2.4/site-packages/yum/config.py", line 27, in ? from parser import ConfigPreProcessor File "/usr/lib/python2.4/site-packages/yum/parser.py", line 3, in ? import urlgrabber File "/usr/lib/python2.4/site-packages/urlgrabber/__init__.py", line 53, in ? from grabber import urlgrab, urlopen, urlread File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 412, in ? import keepalive File "/usr/lib/python2.4/site-packages/urlgrabber/keepalive.py", line 339, in ? class HTTPSHandler(KeepAliveHandler, urllib2.HTTPSHandler): AttributeError: 'module' object has no attribute 'HTTPSHandler' 我试图更新python，看看是否会修复库：
rpm -Uvh python-2.4.3-44.el5.x86_64.rpm
但重启后没有任何改变，所以我决定看看有什么问题：
prelink -all rpm -Va
这导致了很多不满意的依赖关系：
Unsatisfied dependencies for gnome-panel-2.16.1-7.el5.i386: libpangocairo-1.0.so.0 Unsatisfied dependencies for gtkhtml3-3.16.3-1.el5.i386: libpangocairo-1.0.so.0 Unsatisfied dependencies for libgnomeui-2.16.0-5.el5.i386: libpangocairo-1.0.so.0 ... missing /lib/libz.so.1 missing /lib/libz.so.1.2.3 missing /usr/lib/libz.so.1 missing /usr/lib/libz.so.1.2.3 Unsatisfied dependencies for Nessus-4.4.0-es4.i386: libcrypto.so.4, libssl.so.4 ...
我不确定什么提供libpangocairo-1.0.so.0 ，也不是rpm ，所以我开始检查什么提供了libz.so.1并尝试更新它：
[root@...]# rpm -q --whatprovides libz.so.1 zlib-1.2.3-4.el5.i386 [root@...]# rpm -Uvh --force zlib-1.2.3-4.el5.i386.rpm Preparing... ########################################### [100%] 1:zlib ########################################### [100%]
更新之后， libz.so.1和libz.so.1.2.3仍然不存在于/usr或/usr/lib ，并且运行rpm -Va仍然报告这些文件丢失。
当我尝试find / -name 'libz.so.1 ，唯一的结果是在/lib64和/usr/lib64 ，我相信它来自也安装的软件包的x86_64版本。
我应该如何继续？
