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
1 | yum remove yum |
然后就杯具了...
1 2 | [root@localhost ~]# yum -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 2 3 | rpm -ivh --nodeps http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | [root@localhost ~]# yum There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: libxml2.so.2: cannot open shared object file: No such file or directory 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: 2.4.3 (#1, Nov 11 2010, 13:30:19) [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] If you cannot solve this problem yourself, please go to the yum faq at: |
因为yum调用的是python,运行 Python，试下是否可行

提示缺少libxml2.so.2，安装一下试试

再次测试运行下yum命令，结果正常了，大喜

最后，赶紧更新一下系统吧
