ssh cannot create .ssh directory when called from command prompt

[H.Hiro(Maraigue)]

Because MSYS2 executables can be launched from command prompt (cmd.exe), I often use it.
However, I found a problem when I use ssh from command prompt.

The error message is:
Could not create directory '/home/USERNAME/.ssh'.

With the same reason, ssh cannot find the key files and thus I cannot use ssh from command prompt.

Are there any solution?

The version shown by "ssh -V" is "OpenSSH_7.1p2, OpenSSL 1.0.2h 3 May 2016".

Try:

c:\msys64\usr\bin\bash.exe -c "/usr/bin/ssh <user>@

"

also, make sure you have keys generated. Open an msys prompt and run:

ssh-keygen -A

Thanks,
It's a possible alternative, but, honestly, I don't want to change the command...
And, in addition, I want to know why this doesn't work via command prompt.

Perhaps, path name is not correctly converted when MSYS2 app is launched from command prompt. But, if it is true, why what is happened?
