You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-treeoption for single commands, or the GIT_WORK_TREEenvironment variable. There is also the core.worktreeconfiguration option but it will not work in a bare repository (check the man page for what it does).
您的存储库是空的，即它没有附加的工作树。你可以在本地克隆它来为它创建一个工作树，或者你可以使用其他几个选项之一来告诉 Git 工作树在哪里，例如--work-tree单个命令的选项或GIT_WORK_TREE环境变量。还有core.worktree配置选项，但它不能在裸存储库中工作（查看手册页了解它的作用）。
# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status
