你是在用一个分离的脑袋工作吗?

如:

指示您的最新提交不是分支头。

警告:以下是一个git重置——很难:如果你想保存当前修改的文件，请确保首先使用git stash。

$ git log -1
# note the SHA-1 of latest commit
$ git checkout master
# reset your branch head to your previously detached commit
$ git reset --hard <commit-id>

正如git签出手册页中提到的(重点是我的):

有时能够签出不在分支顶端的提交是有用的。 最明显的例子是在标记的官方发布点检出提交，就像这样:

$ git checkout v2.6.18

Earlier versions of git did not allow this and asked you to create a temporary branch using the -b option, but starting from version 1.5.0, the above command detaches your HEAD from the current branch and directly points at the commit named by the tag (v2.6.18 in the example above). You can use all git commands while in this state. You can use git reset --hard $othercommit to further move around, for example. You can make changes and create a new commit on top of a detached HEAD. You can even create a merge by using git merge $othercommit. The state you are in while your HEAD is detached is not recorded by any branch (which is natural --- you are not on any branch). What this means is that you can discard your temporary commits and merges by switching back to an existing branch (e.g. git checkout master), and a later git prune or git gc would garbage-collect them. If you did this by mistake, you can ask the reflog for HEAD where you were, e.g. $ git log -g -2 HEAD

虽然git push表示“所有内容都是最新的”，但从技术上讲，你仍然可以推送一个分离的HEAD，正如Jonathan Benn在评论中所指出的那样

 git push origin HEAD:main

您必须指定目标分支，因为源不是分支，也没有上游目标分支。

我的问题是本地分支与远程分支的名称不同。我可以通过以下方法来推动:

$ git push origin local-branch-name:remote-branch-name

(来源:https://penandpants.com/2013/02/07/git-pushing-to-a-remote-branch-with-a-different-name/)

验证您没有篡改远程URL。

I just wanted to also mention that I ran into this after enabling Git as a CVS in a local Jenkins build configuration. It appears that Jenkins checked out the most recent commit of the branch I gave it and also reset my remote to correspond to the paths I gave it to the repo. Had to checkout my feature branch again and fix my origin remote url with 'git remote set-url'. Don't go pointing a build tool to your working directory or you'll have a bad time. My remote was set to a file path to my working directory, so it naturally reported everything up-to-date when I attempted to push changes with the same source and destination.

我犯过的另一个非常简单却又愚蠢的错误:我只是忘记在提交时添加message -m修饰符。所以我写道:

git commit 'My message'

而不是正确的:

git commit -m 'My message'

注意:它不会抛出任何错误!但是你将不能推送你的提交，而总是让Everything更新

在我的例子中，问题的原因是我在git bash中的符号链接文件夹中执行git推/拉命令! 我在一个git项目中的符号链接文件夹中指向另一个git项目，git的pull/push命令正在回答Everything - latest。 当我将(cd)移动到实际文件夹的路径(不是通过符号链接)时，git的推/拉命令起作用了。

我也有同样的问题。在我的例子中，这是因为必须为同一个遥控器命名。它创建了标准的“起源”，但我已经使用“github”作为我的遥控器很长一段时间了，所以它也在那里。只要我移除了“origin”遥控器，错误就消失了。
