Linux prompts:-bash: / usr/bin/yum: No such file or directory solution after entering yum

Today, when I was installing the program, I found that there was a plug-in that was not installed, so I typed a command without even looking at it.

Yum remove yum

And then it was terrible.

[root@localhost ~] # yum-bash: / usr/bin/yum: No such file or directory

This careless hand didn't paralyze the whole system, but yum didn't work. So, I tried to do something about it.

Rpm-ivh-nodeps http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm 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 rpm-ivh-nodeps http://mirrors.163.com/centos/5/ Os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm

On the explanation of rpm-nodeps

-- nodeps don't verify package dependencies

Next, try typing yum again, resulting in an inexplicable error again

[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: http://wiki.linux.duke.edu/YumFaq

Because yum calls python, run Python to see if it is feasible

[root@localhost~] # python Python 2.4.3 (# 1, Nov 11 2010, 13:30:19) [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

Note that libxml2.so.2 is missing. Try to install it.

Rpm-ivh http://mirrors.163.com/centos/5/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.8.x86_64.rpm

Test again and run the yum command, the result is normal, overjoyed

Finally, update the system quickly.

Yum update

All right, so the yum problem is completely solved! You can give it a try. Thank you for your support.
