git - 为什么flutter pub找不到我的github ssh-key？

Question

我的 flutter 应用程序依赖于一个私有(private)托管在 github 上的模块。
当我运行 pub get从 Powershell，我得到:

Git error. Command: `git clone --mirror ssh://git@github.com:dirkbo/repo-name.git C:\src\flutter\.pub-cache\git\cache\repo-name-123ba`
stdout:
stderr: Cloning into bare repository 'C:\src\flutter\.pub-cache\git\cache\repo-name-123ba'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
exit code: 128

当我复制失败的命令并直接在同一个 powershell 中运行时:

git clone --mirror git@github.com:dirkbo/repo-name.git C:\src\flutter\.pub-cache\git\cache\repo-name-123ba

一切正常:

Cloning into bare repository 'C:\src\flutter\.pub-cache\git\cache\repo-name-123ba'...
Enter passphrase for key '/c/Users/dirkb/.ssh/id_rsa':
remote: Enumerating objects: 229, done.
remote: Counting objects: 100% (229/229), done.
remote: Compressing objects: 100% (132/132), done.
remote: Total 229 (delta 13), reused 229 (delta 13), pack-reused 0
Receiving objects: 100% (229/229), 19.32 MiB | 1.45 MiB/s, done.
Resolving deltas: 100% (13/13), done.

在我的 pubspec.yaml我试过:

repo:
    git: ssh://git@github.com/dirkbo/repo-name.git

(结果见上)
和

repo:
    git: git@github.com:dirkbo/repo-name.git

这给了我:

Git error. Command: `git fetch`
stdout:
stderr: git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
exit code: 128

好像批处理命令正在运行 pub get找不到我的 ssh key 。

问题是 Windows 没有使用正确的 ssh 程序，而不是 openssh 使用的是它的内部 ssh 程序，它当然不知道我在 openssh 中的 key 。git config --global core.sshCommand "'C:\Windows\System32\OpenSSH\ssh.exe'"所以配置git使用OpenSSH后，flutter pub get找到我的 key ，要求输入密码并正确 pull 出包裹。
