1. fatal: 'origin' does not appear to be a git repository

git pull origin master     

fatal: 'origin' does not appear to be a git repository

fatal: Could not read from remote repository.

git仓库中没有origin分支

解决：

git remote -v
 git remote add main git@github.com:QVChen/test_dds.git//仓库复制
// git remote add [<options>] <name> <url>

如图

2. error: failed to push some refs to 'XXXX.git'

git push -u -origin main//输入后报错

解决：

git pull --rebase origin main

没仔细看按Y不停重复，试了下按N，完成rebase

然后

 git push -u -origin main

push成功
