这只是意味着 git 不写任何对象。当所有对象都已经在远程并且合并时,您只需将标签“main”移动到最新提交,就会发生这种情况。我只是做了一个快速测试来证明:
~/workspace
$ git clone git@github.com:korin/test_merge.git
Cloning into 'test_merge'...
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)

~/workspace
$ cd test_merge

$ git co -b test
Switched to a new branch 'test'
~/workspace/test_merge
$ echo 'a' > a
~/workspace/test_merge
$ git add .
~/workspace/test_merge
$ git ci -m 'a'
