git push失败：存在超过100MB的文件

报错原因：

commit的文件list中存在大文件，导致无法push

解决方法：

移除本次commit中的大文件

1. 移除大文件

从报错信息中查找哪些文件出错，然后使用命令git rm --cached 删除指定文件

• File logs/unsup-Stack/DyHATR_small_0.001000/entity2vec is 89.35 MB
  • $ git rm --cached logs/unsup-Stack/DyHATR_small_0.001000/entity2vec
• File dataset/dblp/dblp.xml is 2941.48 MB; this exceeds GitHub’s file size limit of 100.00 MB
  • $ git rm --cached dataset/dblp/dblp.xml

或者使用命令 find ./ -size +100M 查询所有大于100MB的文件

$ find ./ -size +100M
./.git/objects/pack/pack-3492a80b3ed78f8a83a2a1f8fd206e011fc9ee74.pack
./dataset/dblp/dblp.xml

rm后的状态：

$ git status

On branch master
Changes to be committed:
  (use "git restore --staged ..." to unstage)
        deleted:    dataset/dblp/dblp.xml
        deleted:    logs/unsup-Stack/DyHATR_small_0.001000/entity2vec

Untracked files:
  (use "git add ..." to include in what will be committed)
        dataset/dblp/dblp.xml
        logs/unsup-Stack/DyHATR_small_0.001000/entity2vec

2. 重新提交

编辑commit log，完成后:wq保存退出

git commit --amend

此时的状态为：

$ git status
On branch master
Untracked files:
  (use "git add ..." to include in what will be committed)
        dataset/dblp/dblp.xml
        logs/unsup-Stack/DyHATR_small_0.001000/entity2vec

nothing added to commit but untracked files present (use "git add" to track)

然后正常 git push 即可

如果上述操作完成后还是无法解决问题，则可以运行如下命令删除有关某个文件的push操作：

git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch '

最后使用命令git gc 清除本地仓库缓存
