Git 应用问题（一） —— failed to push some refs to git

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

From github.com:Gerrard-Feng/jdbc

 * [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。

Gerrard@LAPTOP-79570TK2 MINGW64 /g/github-workspace/jdbc (master)
$ git push --set-upstream origin master
