起因

小威wei yum update了一把，结果yum就报错了，Python版本并没有升级，依然是2.7.5版本。

报错信息

[root@localhost ~]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
 
   No module named gzip
 
Please install a package which provides this module, or
verify that the module is installed correctly.
 
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Aug  4 2017, 00:39:18) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
 
If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

解决过程

No module named gzip报错提示没有gzip，一开始以为是系统的gzip木有了，跑去清华大学的mirrors上面把gzip包download安装了一下发现yum还是顽强的报错No module named gzip。仔细阅读报错信息后确认这个报错跟Python有关系，于是就进入Python import了一下gzip，果然报错了。

 
[root@localhost ~]# python
Python 2.7.5 (default, Aug  4 2017, 00:39:18) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gzip
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named gzip

找到病根就好治病了，跑到另外一台服务器上面去，查看了一下gzip模块的位置（python的模块其实就是几个文件），拷贝到这台服务器上面就可以了。

登陆到我博客的服务器(腾讯云服务器)看一下gzip模块的位置并下载下来。

 
[root@qcloud ~]# python
Python 2.7.5 (default, Aug  4 2017, 00:39:18) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gzip
>>> print gzip.__file__
/usr/lib64/python2.7/gzip.pyc
[root@qcloud ~]# cd /usr/lib64/python2.7/
[root@qcloud python2.7]# ls gzip.py
gzip.py   gzip.pyc  gzip.pyo    # gzip模块就是这三个文件

拷贝这三个文件(gzip.py gzip.pyc gzip.pyo)到服务器相同位置下面。

 
[root@localhost ~]# cd /usr/lib64/python2.7
[root@localhost python2.7]# rz
[root@localhost python2.7]# rz
[root@localhost python2.7]# rz

再来import一下gzip模块，测试一下模块是否恢复成功。

 
[root@localhost python2.7]# python
Python 2.7.5 (default, Aug  4 2017, 00:39:18) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gzip # 没有报错

gzip模块import成功了，再来看下yum是否可用。

 
[root@localhost python2.7]# yum
Loaded plugins: fastestmirror
You need to give some command
Usage: yum [options] COMMAND
 
List of Commands:
 
check          Check for problems in the rpmdb
.....

执行了一下yum，发现已经正常了(最好是yum clean all一下)。来install一个软件测试一下还有没有暗病。

 
[root@localhost python2.7]# yum -y install htop
Loaded plugins: fastestmirror

好了，软件可以安装，问题成功解决了，但是至于为什么yum update一下就把gzip模块搞废了，还得详细的查看一下”案发现场”才知道了。
