Flutter Run 不起作用，在 iPhone 上启动应用程序时出错
Sou*_*Raj 7 flutter flutter-test
我最近更新了flutter版本。在那之后，flutter run 在 iPhone 上不起作用。我正在使用安卓工作室。android studio 上的运行按钮也不适用于 iPhone，但模拟器工作正常。
我收到以下错误。我已将跑步者模式设置为发布。仍然没有运气。
“在 Raj iPhone 上启动应用程序时出错。”
颤振版本。
Flutter (Channel master, 1.24.0-8.0.pre.374, on Mac OS X 10.15.7 19H2 darwin-x64, locale en-GB)
我没有收到任何其他错误。所以我运行 flutter run -verbose 我得到以下信息

我已经完成flutter clean并再次检查。还是一样的问题。
谢谢
在 中flutter/packages/flutter_tools/lib/src/ios/devices.dart，找到以下代码块：
_logger.printTrace('Application launched on the device. Waiting for observatory port.');
Uri localUri;
try {
localUri = await observatoryDiscovery.uri.timeout(const Duration(seconds: 30));
} on TimeoutException {
await observatoryDiscovery.cancel();
}
将超时增加到更大的数字，例如，60 秒为我修复了它：
localUri = await observatoryDiscovery.uri.timeout(const Duration(seconds: 60));
另外，删除缓存的二进制文件以强制重新生成快照：
rm /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.stamp /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.snapshot
