git error : Updates were rejected because the tip of your current branch is behind

• git error

 

Updates were rejected because the tip of your current branch is behind its remote counterpart. Integrate the remote changes (e.g. 'git pull ...') before pushing again. 

 

• Cause

 

First, I already had a remote origin.

$ git push -u origin main
To github.com:mellamonaranja/PrefixSpan.git
 ! [rejected]        main -> main (non-fast-forward)
error: failed to push some refs to 'git@github.com:mellamonaranja/PrefixSpan.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.

 

Second, the commits are defferent between exist remote origin(tree) and local tree. (Or there have been changes on the remote branch that you don’t have locally.)

$ git status
On branch main
Your branch and 'origin/main' have diverged,
and have 3 and 12 different commits each, respectively.#<<<<<<
  (use "git pull" to merge the remote branch into yours)

 

Therefore it sent me back as "Integrate the remote changes (e.g. hint: 'git pull ...') before pushing again." meaning I need to merge remote branto into local.

 

• Solution

 

Remove git.

#Linux or Mac

$ rm -rf .git/

 

# Windows

$ rm -r -fo .git/

 

 

And push again.

$ echo "# docker-compose_jupyternotebook" >> README.md
