最近項目開發用到git，導師使用的是碼云。
在Windows環境中使用Git連接碼云，嘗試push文件時報錯：

*! [rejected] master -> master (fetch first)
error: failed to push some refs to ‘git@gitee.com:huankai7/practice.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.
hint: See the ‘Note about fast-forwards’ in ‘git push --help’ for details.

如圖：

找了很多方法都是針對github的，最后找到一句命令行

$ git pull gitee master --allow-unrelated-histories

執行后成功上傳。
