visual-studio-2013 - xamarin 应用程序无法在 Visual Studio 2013 中部署

Question

我尝试了更多来运行我的 Xamarin 应用程序。它成功构建，但在尝试调试时，出现以下异常。

据我所知，有一些错过的包裹，因为

Unexpected install output: Error: Could not access the Package Manager. Is the system running?

消息显示在部署状态消息下方。

调试输出

您是否使用基于 ARM 的模拟器(我遇到了同样的问题)？

如果是，那么它们非常慢，并且在启动它们之前无法部署应用程序。

使用基于 x86 的模拟器，这些不是那么快，但至少可以忍受。

在任何情况下(x86 或 ARM)首先启动你的模拟器，然后等到你看到主屏幕。
