我运行了 Get-Help，它询问我是否要运行 Update-Help，我照做了。
如何从 powershell CLI 中获得有关使用 Posh-SSH 的帮助？

也许我只是用错了语法。
或者，可能没有正确安装。从另一个控制台：
`PS C:\Users\thufir> PS C:\Users\thufir> 帮助 New-SSHSession
名称 新 SSH 会话
句法
别名 无
备注 无
PS C:\Users\thufir>
`
更新帮助似乎挂在具有管理员权限的新控制台中：

Try the new cross-platform PowerShell https://aka.ms/pscore6
PS C:\WINDOWS\system32> Update-Help -Force -Verbose -ErrorAction SilentlyContinue
