Vscode-remote-release: "ssh: command not found" when connecting to host

[bobyuxinyang]

Issue Type: Bug

I got "ssh: command not found" when I was running "Remote: Connect to Host" on my mac.
I can run ssh command and connect to my hosts correctly via Terminal.

My system is macOS 10.15 (19A558d).
Remote-SSH @ 0.46.0

UPDATE
this error was on vscode 1.38-stable
I try vscode 1.39.0-insider and reinstall all extensions and it works~
