如果这个文件是你最近一次提交时添加的，而且你还没有推送到远程存储库，你可以删除这个文件并修改提交。

git rm --cached giant_file
    # Stage "giant_file" for removal with "git rm"
    # Leave it on disk with "--cached". if you want to remove it from disk
    # then ignore the "--cached" parameter
git commit --amend -CHEAD
    # Commit the current tree without the giant file using "git commit"
    # Amend the previous commit with your change "--amend" 
    # (simply making a new commit won't work, as you need
    # to remove the file from the unpushed history as well)
    # Use the log/authorship/timestamp of the last commit (the one we are
    # amending) with "-CHEAD", equivalent to --reuse-message=HEAD
git push
    # Push our rewritten, smaller commit with "git push"

所以我遇到了一个特殊的情况:我从gitlab克隆了一个存储库，其中包含一个大于100 mb的文件，但在git历史的某个时刻被删除了。后来，当我添加了一个新的github私人回购，并试图推到新的回购，我得到了臭名昭著的“文件太大”错误。到此为止，我不再能够访问原始的gitlab回购。然而，我仍然能够在我的机器上的LOCAL存储库上使用bfg-repo-cleaner推送到新的私有github回购:

$ cd ~
$ curl https://repo1.maven.org/maven2/com/madgag/bfg/1.13.0/bfg-1.13.0.jar > bfg.jar
$ cd my-project
$ git gc
$ cd ../
$ java -jar bfg.jar --strip-blobs-bigger-than 100M my-project
$ cd my-project
$ git reflog expire --expire=now --all && git gc --prune=now --aggressive
$ git remote -v # confirm origin is the remote you want to push to
$ git push origin master

我尝试了以上所有的方法，但没有一个对我有效。

然后我想出了自己的解决办法。

First of all, you need a clean, up-to-date local repo. Delete all the large files. Now create a new folder OUTSIDE of your repo folder and use "Git create repository here" to make it a new Git repository, let's call it new_local_repo. This is it! All above methods said you have to clean the history..., well, I'm sick of that, let's create a new repo which has no history at all! Copy the files from your old, messed up local repo to the new, beautiful repo. Note that the green logo on the folder icon will disappear, this is promising because this is a new repo! Commit to the local branch and then push to remote new branch. Let's call it new_remote_branch. If you don't know how to push from a new local repo, Google it. Congrats! You have pushed your clean, up-to-date code to GitHub. If you don't need the remote master branch anymore, you can make your new_remote_branch as new master branch. If you don't know how to do it, Google it. Last step, it's time to delete the messed up old local repo. In the future you only use the new_local_repo.

当我的iOS项目没有gitignore文件时，我就遇到了这个问题

我想它可能是想把一个巨大的文件推送到github而github可能拒绝了这个巨大的文件或(多个文件)

我提出了一个非正统但简单的解决方案:

忘记你最近有问题的本地git存储库，git将你的存储库克隆到一个新的目录中。 Git远程添加上游<你的github代表这里> Git拉上游高手 在这一点上，只需复制您的新文件提交，从旧的可能包括您现在减少的大文件到您的新本地代表。 Git添加。 Git commit -m "你的提交文本在这里" Git push origin master

瞧!对我来说很管用。

这对我很管用。来自github的文档 压缩Git提交 Git重置原点/master

git checkout master && git pull;
git merge feature_branch;
git add . --all;
git commit -m "your commit message"
