将 Visual Studio (w Xamarin) 连接到 Mac

Question

我有一台安装了 OSX 10.11 的完整 Mac，具有运行 Xamarin for iOS 所需的一切。
我在 Windows 10 笔记本电脑上安装了 Visual Studio 2015 并收到以下错误：

无法使用 ssh 密钥进行身份验证。请先尝试使用凭据登录

然后我在 W7 PC VS2015 上安装了相同的笔记本电脑的最新版本，并在相同的网络下尝试了相同的连接：完美无瑕。 一切都形成了稳定的渠道。
笔记本电脑上的防火墙与另一台 PC 上的防火墙一样，允许 Xamarin 在 LAN 上进行通信。
在笔记本电脑和 PC 上，我可以在不到一秒的时间内通过 ssh 远程登录 Mac。

这是笔记本电脑的日志：

我不应该只使用 PC 吗？不，启动 Visual Studio 需要将近 10 分钟！ 提前感谢您的帮助。

Answer 1

听起来你的 Win 10 笔记本电脑有用于无密码登录的 ssh 密钥，并且可能（或没有）该密钥已添加到你 Mac 上的 authorized_keys 文件中的 ~/.ssh（/Users/<username>/.ssh 的快捷方式），但是使用 ssh 密钥的登录不起作用，可能是由于权限问题。上面日志的相关行：

Xamarin.Messaging.VisualStudio.Exceptions.MessagingAuthenticationException：无法使用 SSH 密钥对用户“gianventotto”进行身份验证。请检查 $HOME 文件夹和 ~/.ssh/authorized_keys 是否具有使用 SSH 的适当权限。更多详细信息：权限被拒绝（公钥）。 ---> Renci.SshNet.Common.SshAuthenticationException：权限被拒绝（公钥）。

也许尝试从 Mac 上的 authorized_keys 文件中删除您的 Win 10 ssh 密钥，然后使用您的用户名和密码从 VS 登录？
