What should I do if CentOS prompts that the command cannot be found when executing the sudo command?

First switch to the root user and edit the file /etc/sudoers as the root user:

# vim /etc/sudoers

Then find Defaults env_reset and change it to Defaults !env_reset. Then wq! force save and exit.

Then, switch back to a normal user, such as the user name is xx, edit the configuration file in the user root directory ~/.bashrc

# su xx
$ vim .bashrc

Append

alias sudo='sudo env PATH=$PATH'

# at the end of the file ##Finally, make the configuration file take effect

$ source ~/.bashrc
