ios - 找不到虚拟设备 - Ionic Cordova Emulate iOS

Question

我正在尝试在 iOS 中模拟我的 Ionic 应用程序，但是当我运行 ionic cordova emulate ios 时，我收到一个错误:

No target specified for emulator. Deploying to undefined simulator
Device type "com.apple.CoreSimulator.SimDeviceType.undefined" could not be found.

似乎即使在我的 OSX 上有可用的模拟器，但 Ionic 出于某种原因无法访问它们。为什么明明有设备可以在其他地方运行，却在 Ionic 中找不到设备？这可能是环境变量的问题吗？

供引用: ionic 信息:

cli packages: (/usr/local/lib/node_modules)

    @ionic/cli-utils  : 1.19.2
    ionic (Ionic CLI) : 3.20.0

global packages:

当我运行 ionic cordova emulate ios --list 时，我得到以下输出:

Available ios virtual devices:

但是，当我运行 ios-sim showdevicetypes 时，我得到:

这里有很多代码，因为它需要输出日志。

Answer 1

或者你可以尝试这样的事情:

cd platforms/ios/cordova
npm install ios-sim@latest
