git远程仓库在本地看不到&push 到远程仓库失败的解决方案

今天想把在公司写的一些代码上传的github上，将本地仓库和远程仓库关联起来，执行： 【git push -u origin main 】 把本地main branch的代码推送到远程的main branch时，报错：

  ! [rejected] main -> main (fetch first)
  error: failed to push some refs to 'github.com:hijack-621/tpr-website.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.

查资料发现是因为我们在本地新建库后，与远程仓库的内容不一致导致的（远程仓库有一些内容本地没有）。

而且去查看远程分支：

Administrator@MS-TQHELRTLDMXE MINGW64 /d/phpstudy/WWW (develop)
$ git branch -a
* develop
  main
//只看到本地的分支！！！

 

 使用命令：git remote update origin --prune   --prune 去更新远程分支

再次查看所有分支：

Administrator@MS-TQHELRTLDMXE MINGW64 /d/phpstudy/WWW (main)
$ git branch -a
  develop
* main
  remotes/origin/develop
  remotes/origin/main

但是执行 【git push -u origin main 】 仍旧报错

! [rejected] main -> main (non-fast-forward)
error: failed to push some refs to 'github.com:hijack-621/tpr-website.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.

意思大致是：你现在的分支被隐藏了...

不明白为什么会被隐藏【是不是我开了两个git bash 窗口， 用的同一个sshkey去操作的原因】，难怪 使用 -a  参数查看所有分支时，看不到远程分支呢。。。=   》》 解决方案：

使用 --force 参数，强制去提交【完成命令  git push -u --force origin main 】【推送本地git中的文件到远程的 main分支中】。【这里是 使用 gir push --help 】帮助命令时，在git 官方提供的 git-push manual page 页面中找到的方案！ 下面是官方的解释！

--force
Usually, the command refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it. Also, 
when --force-with-lease option is used, the command refuses to update a remote ref whose current value does not match what is expected.

This flag disables these checks, and can cause the remote repository to lose commits; use it with care.

Note that --force applies to all the refs that are pushed, 
hence using it with push.default set to matching or with multiple push destinations configured with remote.*.push may overwrite refs other than the current branch (including local refs that are strictly behind their remote counterpart). 
To force a push to only one branch, use a + in front of the refspec to push (e.g git push origin +master to force a push to the master branch).
 See the <refspec>... section above for details.
