在windows安装完ssh-agent，添加多个ssh key之后,git clone依旧提示Permission Denied。
Git需要知道Windows ssh-agent服务的位置， 可以通过添加
Git for Windows uses the ssh binaries included with git by default. While this works well enough in most situations, one side-effect is that git has no idea how to talk to the Windows ssh-agent service. In order for git commands to use the Windows ssh-agent service, git needs to be informed of the system OpenSSH path. To accomplish this, the environment variable
GIT_SSHneeds to be set with the path of the system OpenSSH executable.
Run the following command to update the environment variable:
PS > [Environment]::SetEnvironmentVariable("GIT_SSH", "$((Get-Command ssh).Source)", [System.EnvironmentVariableTarget]::User)
