git 克隆失败，“--stdin 需要 git 存储库”
git clone failure with "--stdin requires a git repository"
我对这个问题很困惑，一直卡在这里，不知道为什么会这样。
我正在使用 git 克隆从 bitbucket 中获取我的 repo，例如 "git clone git@bitbucket.org:mycompny/therepo.git "
但是，我失败了：
fatal: --stdin requires a git repository
fatal: index-pack failed
您可以看到错误消息 introduced in 2016 here:
The index-pack builtin is marked as RUN_SETUP_GENTLY, because it's perfectly fine to index a pack in the filesystem outside of any repository.
However, --stdin mode will write the result to the object database, which does not
make sense outside of a repository. Doing so creates a bogus ".git" directory with nothing in it except the newly-created pack and its index.
错误原因是当前文件夹不是git目录。
检查您当前的文件夹，并确保其路径是现有文件夹。
这里的根本原因是使用了 Cygwin，而不是 Git For Windows 中包含的 git bash。
OP yunfei adds :
If I use the git included from my "git bash", by exporting it into my environment in cygwin, I can make it work from cygwin as well.
Just do export PATH="/cygdrive/c/Program Files/Git/cmd":$PATH
Cygwin 必须包含一个 Git 版本（2.21 in the Cygwin package list) which was not compatible with other components from Git for Windows：使用 Git 中的 git.exe 对于 Windows 更安全。
