由于不存在大文件导致git push错误

尝试推送到git时,我一直得到相同的结果:

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@github.com:mas-dse/gbrock.git'

问题是,txt文件不再存在.我对ipython笔记本进行了更改,删除了该文本文件.保存了笔记本.添加了对git的更改.承诺改变.然后尝试推送git,但它不想工作.

我不能用:

git rm --cached 'file' 

因为该文件不再存在.我不知道该做什么.任何帮助将非常感激.
