问题1.先创建本地库，后拉取远程仓库时上传失败的问题怎么解决？

操作主要步骤： 

        step1 设置远程仓库地址: 

        $ git remote add origin git@gitee.com:yourAccount/reponamexxx.git

        step2 推送到远程仓库:

        $ git push -u origin "master" 

报错信息：

To gitee.com:konallzong/technical-books.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'gitee.com:yourAccount/reponamexxx.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.

解决办法： 

         step1 拉取远程仓库，使用 --allow-unrelated-histories选项，本质上是合并(merge):

        $ git pull origin master --allow-unrelated-histories

        

 

        step2:在来一把，不带该选项。

        $ git pull origin master

         step3:推送

        $ git push -u origin "master"
