linux输入yum后提示： -bash: /usr/bin/yum: No such file or directory的解决方案
今天在安装程序时，发现有一个插件未安装，我就随手敲了一个命令,看都没看
yum remove yum
然后就杯具了...
1
[root@localhost ~]# yum
2
-bash: /usr/bin/yum: No such
file
or directory
这个粗心的手误倒不至于让整个系统瘫痪，yum 却无法使用了。于是，我试着折腾了一番
1
rpm -ivh --nodeps http:
//
mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm
2
rpm -ivh --nodeps http:
//
mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
3
rpm -ivh --nodeps http:
//
mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm
关于rpm --nodeps的解释
1
--nodeps don
'
t verify package dependencies
接下来，再次尝试输入yum,结果再次出现莫名错误
1
[root@localhost ~]# yum
2
There was a problem importing one of the Python modules
3
required to run yum. The error leading to this problem was:
4
5
libxml2.so.

: cannot open shared

file
: No such

Please
install
a package
which
provides this module, or
8
verify that the module is installed correctly.

It
'

current version of Python,

If you cannot solve this problem yourself, please go to
16
the yum faq at:

http:
//
wiki.linux.duke.edu/YumFaq
因为yum调用的是python,运行 Python，试下是否可行
