github - git push not working

Question

After git push, I checked github and found that there is no edge

git add --all
git commit -m 'commit'
git push -u origin gh-pages

The command is correct, but why can’t it achieve the expected effect?

Answer 1

-m cannot be empty

Answer 2

Pay attention to the commit in your picture, the next line will echo aborting commit due to empty commit message

Answer 3

This prompt means that the current warehouse and the remote warehouse are already synchronized!
