Input yum error in CentOS: sudo:unable to execute/bin/yum:no such file or directory

After today's attempt to update the Python version under virtual machine CentOS.

Run "Yum" command, Error: "Sudo:unable to execute/bin/yum:no such file or directory"

Query the next online data found that the original Yum call is written in Python. I remembered that I had just updated the Python version and forgot to modify the Yum config file.

Workaround: Modify the Yum configuration file

[[Email protected] ~] #vim/usr/bin/yum

Change the #!/usr/bin/python of the file header to #!/usr/bin/python_old//change to the previous version number.

Save and exit, Yum will work.

If there are other commands, the software does not work properly, follow the Yum configuration file modification method, modify its configuration file.
