push的时候报错： #hint: Updates were rejected because the tip of your current branch is behind #hint: its remote counterpart. Merge the remote changes (e.g. 'git pull') #hint: before pushing again. git中的内容与本地中的内容部一直，需要先fetch，然后再merge，最后上传push。 强制push： git push -u origin master -f 定期使用项目仓库内容更新自己仓库内容。 $ git remote add upstream github.com/yeasy/docker_practice $ git fetch upstream $ git checkout master $ git rebase upstream/master $ git push -f origin master
