我正在尝试为嵌入式系统构建一个 yocto 映像，我总是在 linux-intel-ese-lts-5.4 的 do_fletch 上出错
我尝试了一切，还完全恢复了 bitbake 擦除“tmp”、“缓存”和“下载”文件夹
错误是：
致命：无法通过“/home/marco/yocto/build/../managed/linux-intel-ese-lts-5.4/.git/objects”启动迭代器：不是目录
但是 .git 目录存在并且在正确的位置
这里调试：

编辑：我在 build/downloads/git2 中看到我有文件夹，但名称很奇怪：“home.marco.yocto.build ....managed.linux-intel-ese-lts-5.4”
We use repo to manage yocto buildareas and recently see a similar failure。我认为这与最近的 git CVE 修复有关：
https://github.com/git/git/commit/6f054f9fb3a501c35b55c65e547a244f14c38d56
repo 生成带有符号链接的 git 存储库，我认为这就是克隆失败的原因。 bitbake git fetcher 可能需要修复以使用 file:// 或 --no-local 与克隆。
