Git报错 FETCH_HEAD fatal: refusing to merge unrelated histories

1.出现场景

2.出现原因：

本人出现原因：当本地仓库关联远程仓库时，因为本地仓库已经存在文件，同时远程仓库文件已初始化。

执行：

$ git push -u qlll master

$ git push -u qlll master
To https://gitee.com/*****/****.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://gitee.com/smai43_admin/qlll.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.

无法建立关联，需要进行版本控制
尝试下拉版本建立联系

$ git pull qlll master

$ git pull qlll master
From https://gitee.com/smai43_admin/qlll
 * branch            master     -> FETCH_HEAD
fatal: refusing to merge unrelated histories

最后：

git pull qlll master --allow-unrelated-histories

$ git pull qlll master --allow-unrelated-histories
From https://gitee.com/*****/****
 * branch            master     -> FETCH_HEAD

3.解决方法

pull拉取不下最新的原因是
本地仓库和远程仓库的两个分支是不同的版本，所以拉取不下来，需要解决冲突先

在其代码模块后加上这个参数，强制合并，忽视提交的历史，之后通过代码模块的不同进行合并即可

git pull origin master --allow-unrelated-histories
