超级罕见-但仍然:在Windows上，它可能是打包refs有一个带有一个字母大小写的分支(即dev/mybranch)，而refs文件夹有另一个大小写(即dev/mybranch)当核心。Ignorecase设置为true。

解决方案是手动从wrapped -refs中删除相关行。没找到更干净的解决办法。

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

我也遇到过类似的情况;当我做出改变并试图 Git push origin master，它说一切都是最新的。

我必须git添加更改后的文件，然后git push origin master。从那时起，它就开始工作了。

我的错误不同于上面提到的所有错误。如果你不知道为什么你会有一个分离的头，那么你可能不会。我正在使用git commit和git push进行自动驾驶，还没有读取git commit的输出。结果，这是一条错误消息，因为我忘记了-am。

[colin] ~/github/rentap.js [master] M % git commit 'figured out some more stuff with the forms in views and started figuring out row and mode in models so also made matching routes and controllers'
error: pathspec 'figured out some more stuff with the forms in views and started figuring out row and mode in models so also made matching routes and controllers' did not match any file(s) known to git.
[colin] ~/github/rentap.js [master] M % git push
Enter passphrase for key '/home/colin/.ssh/id_ecdsa': 
Everything up-to-date

通过把-am放在我经常做的地方来修复它:

[colin] ~/github/rentap.js [master] M % git commit -am 'figured out some more stuff with the forms in views and started figuring out row and mode in models so also made matching routes and controllers'

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.

另一种需要注意的重要情况是:git的默认状态是您正在“master”分支中工作。在很多情况下，您只需要将其作为主要的工作分支(尽管有些人会变得花哨并做其他事情)。

不管怎样，这只是一个分支。所以我可能会遇到这样的情况:

我的活动分支实际上不是主分支. ...但我习惯执行命令:git push(我之前已经做过git push origin master，所以这是一个快捷方式)。

所以我习惯性地将主分支推到共享回购…对我来说，这可能是一件干净的好事……

但是我已经忘记了我一直在做的改变还没有在主分支!!

因此，每次我尝试git push，当我看到“Everything up to date”时，我都想尖叫，但当然，这不是git的错!它是我的。

因此，我将我的分支合并到master中，然后执行push，一切都恢复正常。
