linux輸入yum后提示： -bash: /usr/bin/yum: No such file or directory的解決方案
今天在安裝程序時，發現有一個插件未安裝，我就隨手敲了一個命令,看都沒看
yum remove yum
然后就杯具了...
1
[root@localhost ~]# yum
2
-bash: /usr/bin/yum: No such
file
or directory
?
這個粗心的手誤倒不至于讓整個系統癱瘓，yum 卻無法使用了。于是，我試著折騰了一番
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
關于rpm --nodeps的解釋
1
--nodeps don
'
t verify package dependencies
接下來，再次嘗試輸入yum,結果再次出現莫名錯誤
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.

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

因為yum調用的是python,運行 Python，試下是否可行

提示缺少libxml2.so.2，安裝一下試試
rpm -ivh http:

再次測試運行下yum命令，結果正常了，大喜
