报错内容：
failed to push some refs to '[email protected]:Sunpro108/Sunpro_Blog.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.
解决方法：
报错信息中也给出了建议，就是要合并另外一个远端修改，执行如下命令：
git pull origin master --allow-unrelated-histories
完美解决！
