git报错

1. git push orgin master

当我输入git push orgin master，将本地仓推送到远程仓的master分支上时，提示错误如下：

 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/elimuzi/python_learning_files.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.

2. git pull orgin master

我以为是要我先拉取远程的代码（我的远程没有代码，只有readme文件）。
于是就输入git pull orgin master，可是还是报错。

fatal: refusing to merge unrelated histories

3. git pull --allow-unrelated-histories

于是我输入git pull --allow-unrelated-histories，然后还是报错。应该是提示我，git branch --set-upstream 本地关联远程分支

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=orgin/<branch> master

4. git branch --set-upstream-to=orgin/master

输入条命令以后，我的本地分支就和远程的分支关联起来了。
而后我输入git pull --allow-unrelated-histories， git push orgin master也都成功了
