今天在本地创建了一个新的 repository，想关联到 Github 上的时候出现问题，如下：
Gerrard@LAPTOP-79570TK2 MINGW64 /g/github-workspace/jdbc (master) $ git push --set-upstream origin master To github.com:Gerrard-Feng/jdbc.git ! [rejected] master -> master (fetch first) error: failed to push some refs to 'git@github.com:Gerrard-Feng/jdbc.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.
在网上搜索了一下这个错误：https://blog.csdn.net/u014470581/article/details/51490480。
发现是因为远程仓库创建的时候有 README.md 这个文件，而本地没有，从而导致 push 出错。
那么解决问题就很简单了，把远程分支上的 README.md 拉下来：
Gerrard@LAPTOP-79570TK2 MINGW64 /g/github-workspace/jdbc (master) $ git pull --rebase origin master warning: no common commits remote: Counting objects: 3, done. remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0 Unpacking objects: 100% (3/3), done. From github.com:Gerrard-Feng/jdbc * branch master -> FETCH_HEAD * [new branch] master -> origin/master First, rewinding head to replay your work on top of it... Applying: First commit.
重新 push，问题解决！
这里还有一个插曲，最初我试图在提交的时候带上一个10MB 的大文件，导致 push 卡死，将这个文件移除 commit 才提交成功。
