【中文标题】架构 x86_64 颤动的未定义符号【英文标题】：Undefined symbols for architecture x86_64 flutter 【发布时间】：2020-08-31 11:38:36 【问题描述】：

我正在开发应用程序。 android工作正常，但在ios没有。我需要一些帮助才能在 ios mobile 上运行它。我正在使用 lib：google_maps_flutter：^0.5.27+3 和 firebase_ml_vision：^0.9.3+8。 Xcode 11.4.1 和 Mac os Catalina 10.15.4。有人知道如何解决这个问题。我还没找到。

flutter doctor
[✓] Flutter (Channel stable, v1.17.0, on Mac OS X 10.15.4 19E287, locale en-BR)
[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[✓] Xcode - develop for iOS and macOS (Xcode 11.4.1)
[✓] Android Studio (version 3.6)
[✓] VS Code (version 1.45.0)

【问题讨论】：

物理设备 (iPhone) 有问题吗？我有 Objective-C Flutter 项目，但尝试使用带有 Swift 代码的插件。用 Swift 重新创建 Flutter 项目为我解决了这个问题 【参考方案1】：

可能错误出在某些XCode项目文件上，试试：

运行此命令

扑干净 && \ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ 扑跑

【讨论】：

我不得不分开运行，但它可以工作。非常感谢:) 完美 - 工作愉快，谢谢。对于 Mac，我使用... flutter clean; rm ios/Podfile ios/Podfile.lock pubspec.lock; rm -rf ios/Pods ios/Runner.xcworkspace; flutter run 对我来说这个答案不起作用。我正在开发一个 Flutter 插件，在我的情况下，解决方案是将 s.static_framework = true 行添加到我插件的 podspec 文件中。希望这可以帮助某人完美。它有效这对我也不起作用。【参考方案2】：

这通常是由于现有缓存而导致的依赖关系解析问题。如果您无法为 iOS 构建，无论插件的版本如何，请执行以下步骤。

注意：建议您时不时执行此操作，这样还会占用您机器上的大量已用空间。

project/ios

pod deintegrate && rm Podfile.lock && pod install

flutter clean

rm -rf ~/Library/Developer/Xcode/DerivedData

Cmd + Shift + K

flutter build ios

【参考方案3】：

在带有 m1 芯片的 mac 中，我无法在模拟器中运行我的项目，而是必须使用连接的物理 iPhone，它没有显示错误，运行良好。
