ios 的expo -“启动设备时无法确定运行时包”

Question

尝试在 Macbook（2012 年中）上启动 expo 项目，出现以下错误：

*** -SimDevice _onBootstrapQueue_bootWithOptions:error:, SimDevice.m:2057 中断言失败 2021-12-25 21:21:29.751 simctl[3424:48740] *** 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“启动设备时无法确定运行时包。”

我该如何解决这个问题？预先感谢。

> expo start --ios

Answer 1

我已经成功解决了这个问题：

使用以下命令单独启动模拟器：
1. open -a Simulator
在此之后，如果您再次运行
2. expo start

    并输入 

   i

   ，模拟器将正常启动。

Answer 2

有完全相同的问题。我的问题是，除了 iOS Simulator 之外，我还需要手动安装 iOS（下面 Xcode 设置平台选项卡上的第三项）。

Answer 3

就我而言，较旧的 XCode 导致了该问题。删除它也会消灭它的模拟器，从而解决了这个问题。对于那些不需要两个版本的人来说，这可能会有所帮助。

Answer 4

就我而言，skywlkr 可以工作，但只有在我更新 Xcode 之后。
