在gitee上新创建项目后，将本地的项目提交到git上去
git init
touch README.md
git add .
git commit -m 'first commit'
git remote add origin https://gitee.com/abc/abc.git
git push -u origin master
将项目push到仓库的时候，因为仓库中的项目非空，所以会报错：
To gitee.com:abc/abc.git ! [rejected] master -> master (fetch first) error: failed to push some refs to 'git@gitee.com:abc/abc.git' hint: Updates were rejected because the remote contains work that you do hint: not have locally. This is usually caused by another repository pushing hint: to the same ref. You may want to first integrate the remote changes hint: (e.g., 'git pull ...') before pushing again. hint: See the 'Note about fast-forwards' in 'git push --help' for details.
所以先pull项目
git pull
git push -u origin master
报错：
To gitee.com:abc/abc.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to 'git@gitee.com:abc/abc.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. hint: See the 'Note about fast-forwards' in 'git push --help' for details.
提示版本落后于线上的项目，线上的内容是没有用的，所以强制推送一次
git push -u -f origin master
成功后创建多个分支：
查看本地分支和远程分支
git branch
git branch -r
创建分支
git checkout -b v1.0 origin/master
git push origin HEAD -u
