问工蜂在线仓库如何减少体积？

按照官方教程尝试缩小体积：

git gc --prune=now

但这个应该只是本地，我执行后还是无法提交，报错如下

Counting objects: 174, done.

Delta compression using up to 4 threads.

Compressing objects: 100% (98/98), done.

Writing objects: 100% (174/174), 86.01 MiB | 2.24 MiB/s, done.

Total 174 (delta 104), reused 121 (delta 64)

应该需要缩减在线库体积，怎么做？
