Question

我正在Mac上使用ReactNative应用程序。我已经安装了XCode6。我转到XCode-> Open Developer Tool-> IOS Simulator。现在，当我在VS Code终端上运行以下命令时，这将启动模拟器

react-native run-ios

我遇到以下错误

info Found Xcode project "MyNewProject.xcodeproj"
Usage: simctl list [devices|devicetypes|runtimes]
error Could not parse the simulator list output. Run CLI with --verbose flag for more details.
Error: Command failed: xcrun simctl list --json devices
Usage: simctl list [devices|devicetypes|runtimes]

我在Google上搜索了很多，但找不到任何有用的信息。任何帮助将不胜感激

Xcode 6已有5年历史。我相信--json是在Xcode 8或Xcode 8中添加到simctl的。如果要使用它，则需要来自较新的Xcode的较新版本的CoreSimulator。

无法在IOS模拟器上运行ReactNative应用
