My problem description:
When I make git pull I have an error:
error: unable to start editor 'emacs'
How can I fix it?
You can fix this problem by setting vim editor as your default git editor. Most linux distro will have vim by default:
To set git editor to vim, we need to execute below command:
git config --global core.editor vim
You could also install emacs editor, but most prople prefered vim over vi and emacs.
