无法为颤振模拟器构建应用程序

Question

我已经做了所有的事情，并在 pod 文件中将 iOS 版本更改为 10，但仍然出现错误。

Could not build the application for the simulator.
Error launching application on iPhone 11.

由于多种原因，可能会发生此错误。

• 首先，它可能是由于一些本机错误而发生的，这可以通过使用 ⌘ + B 在 Xcode 中构建应用程序来发现。如果是这种情况，那么您可以解决错误并尝试在 Xcode 本身中构建应用程序。如果它在构建过程中成功，那么您的应用将从模拟器中运行。

• 其次，如果尚未完成，请尝试从 Xcode 更改 iOS 版本。

• 第三，它可能是由于 pod 中的一些变化而发生的。要解决此问题，请执行以下步骤：

  • rm ios/Podfile

  • flutter pub get 获取包裹。

  • 从目录中的ios文件夹中删除Pods文件夹。

  • cd ios 然后pod install

  • flutter clean

  • 运行项目。 （如果您使用的是 VSCode，请按F5）

希望这能解决您的问题。
