使用git遇到的問題，待解決。

用git 上傳代碼時，遇到了這樣的問題，還沒有找到解決方法，先將問題發上來。

提示信息如下：

git.exe push --progress "origin" master

To https://git.dev.tencent.com/xiawenyou/GpsExchange.git
! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://git.dev.tencent.com/xiawenyou/GpsExchange.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.


git did not exit cleanly (exit code 1) (384324 ms @ 2019/7/9 13:29:49)

 如果你知道怎麼解決，請告知，十分感謝。
