我正在 Flutter 上开发一个应用程序，但是当我在模拟器中运行它来模拟它时，IntelliJIdea 给了我以下错误：

谁能帮忙提点建议？

谢谢

【问题讨论】：

你使用“flutter run”命令吗？我相信不知何故另一个命令正在运行。我认为您的项目配置错误。
@yamin 感谢您的建议，不，我正在尝试从 IntelliJIDEA 运行颤振
@Shahsayyad 你能试试flutter run吗？（并将结果添加到您的问题中，最好使用-v 进行详细输出，这很可能会显示错误）
@creativecreatorormaybenot 我做了什么，Cocoapod 错误停止了。我在 Podfile 中取消了 #use_frameworks! 的注释，错误停止了，Android Studio 给了我一个构建。该应用程序运行顺利，但我担心这不会产生额外的看不见的错误。
朋友们知道如何在 Flutter 应用中使用内嵌视频吗？

通过在 Podfile 中取消注释 use_frameworks，我能够解决这个特殊问题。
