Under ubuntu, the. vimrc file is configured, and then the vi command is used to edit the file and prompt when opening it.
Sorry, the command is not available in this version: syntax on
The contents of the line where the error occurred are
syntax on, this is why?
Ubuntu’s vim is a compact version, of course there is no syntax configuration.
All you need to do is install a full version of vim$ sudo apt-get install vim
