本来想把本地项目上传GitHub一下，打开gitbash,
git init
之前配置过了 用户名和邮箱以及ssh等
$ git remote add origin https://github.com/ljt1018168/Myturn.js.git
建立连接；
git add .
git commit –m '20190101'
然后git push origin master 没有问题吧，我也觉得没有问题
然而额

意思就是先让我pull下，
那我就 git pull origin master
$ git pull origin master
From https://github.com/ljt1018168/Myturn.js
* branch master -> FETCH_HEAD
fatal: refusing to merge unrelated histories
什么玩意拒绝合并？
好吧继续git保护措施防止你合并了不同的仓库。
强制一下：git pull origin master --allow-unrelated-histories
再 git push origin master就能ok啦
