当我尝试构建Flutter项目到IOS时，它显示了这个错误，我尝试清理并尝试更改项目的目录。

Launching lib/main.dart on iPhone 12 Pro Max in debug mode... Running pod install... CocoaPods' output: ↳

Error output from CocoaPods: ↳
    Ignoring ffi-1.12.2 because its extensions are not built. Try: gem pristine ffi --version 1.12.2
Error running pod install

下面是pubspec.yaml文件

cupertino_icons: 0.1.2
  google_maps_flutter: 0.5.27
  mvc_pattern: 5.1.1
  global_configuration: 1.5.0
  http: 0.12.1
  html: 0.14.0+3
  shared_preferences: 0.5.7
  flutter_html: 0.11.1
  location: 3.0.2
  url_launcher: 5.4.5
  firebase_messaging: 6.0.13
  cached_network_image: 2.2.0
  fluttertoast: 4.0.1

我尝试过的事情，从常识和各种其他堆栈问题：

flutter clean
添加到ios/Podfile

post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.0'
       end
     end
  end

flutter pub get
安装gem install ffi --version 1.13.1 --user-install

ios

更新：您可能不需要再这样做了，这取决于您正在使用的版本，如果您有此问题，请遵循后续步骤，但您可能会处于更好的位置，只需遵循官方网站的安装过程。
https://docs.flutter.dev/get-started/install/macos
旧解决方案：在Flutter的官方网站上，当安装Flutter时，他们告诉你如果你使用的是苹果的silicon，就运行这个命令。
已弃用：该网站不再包含此说明。

$ sudo gem uninstall ffi && sudo gem install ffi -- --enable-libffi-alloc

你也可以删除你的ios/Podfile和ios/Podfile.lock
然后运行

flutter clean && flutter pub get && flutter run

只要记住连接您的设备或在模拟器上运行它打开.

我建议尝试运行日志中提到的gem pristine ffi --version 1.12.2，看看它是否有效。这个问题似乎与existing Stack Overflow post类似。

如果您的计算机使用的是M1或M2处理器，那么我建议您尝试以下操作：

sudo arch -x86_64 gem install ffi

arch -x86_64 pod install
