Git：推送被拒绝

我有一个团队，我们正在开发一个项目。我们的一名团队成员在 GitHub 上创建了一个存储库，并将其他人添加为协作者。我的团队成员将我们的代码提交到这个存储库。我对我的部分进行了更改，当我尝试提交它时，出现错误。如何将更改提交到我作为协作者的存储库？

这就是我所做的：

git remote add origin https://github.com/xxx/xxx.git (added a repository where I'm a collaborator)

`git push origin master
To https://github.com/xxx/xxx.git
! [rejected]        master -> master (fetch first)  
error: failed to push some refs to 'https://github.com/xxx/xxx.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. 

git pull origin master
warning: no common commits

* branch            master     -> FETCH_HEAD
* [new branch]      master     -> or/master
fatal: refusing to merge unrelated histories

我只想更新我的部分并将其提交到存储库。我没有自己的存储库。

谢谢

看起来像你们两个master分支已分叉。

# HEAD at your master
$ git checkout master

# your master on a new branch
$ git checkout -b diverged.master

# get origin's master
$ git checkout master
$ git fetch origin master
$ git reset --hard origin/master

# Create a new branch for the diverged feature
$ git checkout -b feature.branch

# Merge your diverged changes into the new feature branch
$ git merge diverged.master

# Do any conflict resolutions

# Merge feature branch to master
$ git checkout master
$ git merge feature.branch

# Push to remote
$ git push origin master

Edit

我错过了关于这是一个全新的仓库的部分..让这变得稍微容易一些

# HEAD at your master
$ git checkout master

# your master on a new branch
$ git checkout -b diverged.master

# delete master branch
# git branch -D master

# pull master from origin
$ git pull origin master

# HEAD at origin's master
$ git checkout origin master
$ git pull # for good measure

# merge your changes
$ git merge diverged.master

# push your changes
$ git push origin master
