git init 后关联github仓库是发生错误：

: failed to push some refs to ‘[email protected]:AlanKnightly/reactC.git‘
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: ‘git pull ...‘) before pushing again.
hint: See the ‘Note about fast-forwards‘ in ‘git push --help‘ for details.

应该在git init后执行

git pull -f  --all

然后再git add 、git commit

虽然输入git pull origin master 等操作无效

网上一查发现最简单的解决办法：

git push -u origin master -f
