Xcode 13 & Flutter 2.5.1 -致命错误:找不到'Flutter/Flutter.h‘文件#import <Flutter/Flutter.h>

Question

我在升级到Xcode 13后才开始遇到这个问题。几天前我把Flutter升级到了2.5.1。

这就是我所看到的：

我尝试过重新安装Flutter，删除并重新克隆我的项目，移除pod，flutter clean +pod install，flutter缓存修复，并从项目中删除Flutter并重新添加。

以上每种情况都会导致上述错误的某种变化。

我还不得不改变我的Podfile --

post_install do |installer|
  installer.pods_project.targets.each do |target|
   target.build_configurations.each do |config|
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
   end
  end
 end

如果我将其还原，那么我会得到一组不同的错误，其中一些pods抱怨设置为8.0，并且需要从9.0到14.9.9。

我尝试更改Runner项目中的各个pod，但不起作用。上面的说明消除了这个错误，但现在我面对的是另一个错误。

值得一提的是，Android运行得很好。只是iOS而已。

对这个有什么其他的建议吗？

Answer 1

这是对我有效的方法：

在Podfile中:替换

post_install do |installer|
  installer.pods_project.targets.each do |target|
   target.build_configurations.each do |config|
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
   end
  end
 end

通过

post_install do |installer| 
  installer.pods_project.targets.each do |target| 
    flutter_additional_ios_build_settings(target) 
  end 
end

然后在Xcode中打开iOS文件，在Pod中，对于每个目标，在Build Settings中，将deployment Target设置为11 (也许9就足够了)

这是你已经尝试过的吗？

Answer 2

在XCode 13和Flutter 2.5.3中有类似的问题:通过xcodebuild构建随机模块的错误(从UI works构建)。在我尝试删除“有问题的”库之后-- error是针对下一个随机库的，直到我坚持使用Flutter.h。

我的问题是，在解决问题的过程中，我在XCode中将部署目标更改为13，但弄得一团糟:我在Podfile，项目->运行器->信息，项目->运行器->构建设置中更新了它，但忘记了在目标->运行器->构建设置中进行更新。

一旦我更新了Targets->Runner->Build Settings，它就开始成功编译了。

最终，我在所有地方都回滚到了Target 11.0，它仍然可以编译。
