git operation push

Question

Answer 1

Try to clone the remote library first, and then push it

git clone https://github.com/aaa/aaa.git(此处是你的库地址)
git add *
git commit -m 'update'
git push -u origin master

Answer 2

Confirm whether the remote library has a master branch.
Confirm whether you have permission to access the remote library.

Answer 3

First, you need to make sure you have write permissions on the associated remote repository.
Then, you need to make sure that the local name of your remote warehouse is origin (use the git remote show command). Although it is this name by default, what if you change it?
