Push rejected: Push to origin/master was rejected
首先，git init (在工程文件夾下)
git remote add [-t <branch>] [-m <master>] [-f] [--[no-]tags] [--mirror=<fetch|push>] <name> <url>
即：（針對問題 Your local changes to the following files would be overwritten by merge）
git remote add <name> <url>
用如下命令檢驗：
git remote -v
然后：
git pull origin master --allow-unrelated-histories git pull origin master
接下來即可push和pull
