“$ git push”branch_name 的致命错误

Question

Why is this not pushing to my newly created branch?

PS `\team_test> git checkout -b 123123
Switched to a new branch '123123'
PS `> git push
fatal: The current branch 123123 has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin 123123

PS ~> git push --set-upstream origin 123123

I was used to push to origin ( git push --set-upstream origin 123123 ), why can't I just push to my own branch without origin ? Why can't I just print "git push" when I'm in my branch?

Answer 1

It doesn't matter that this is "your" branch. It is a new branch so it doesn't exist on the remote. Therefore, in order to push, you have to say what you want done with it. You cannot just say git push .

You have two choices. One is to say every single time what you want done with the branch:

git push origin 123123

However, it is more convenience to say this, once :

git push -u origin 123123

The -u is a shortcut for setting the upstream. Now you will be able to say git push forever on this branch.

You have to do this for every new branch you create on your local repo that you want to push.
