找不到模块'Audio_Session'

我试着在一个带有M1芯片的新Mac上建立一个现有的flutter项目。我面临以下错误：audio_session模块丢失。

有什么想法吗？

终于，找到了解决办法。

不知怎么的，如果我进入flutter项目的iOS文件夹，输入'pod init；pod install'生成了一个基本的Podfile（这意味着它只指定了平台）。

我在某个地方发现了一个帖子，建议删除iOS文件夹中关于pod的所有内容，并在项目中运行flutter run。在project文件夹中运行“flutter run”（也集成了“pod install”），生成了一个非常详细的pod文件，但这一次我遇到了与平台有关的另一个错误（如下所列）。

Error output from CocoaPods:
↳

    [!] Automatically assigning platform `iOS` with version `12.0` on target
    `Runner` because no platform was specified. Please specify a platform for
    this target in your Podfile. See
    `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: To set up CocoaPods for ARM macOS, run:
  arch -x86_64 sudo gem install ffi

我试图按照建议运行上面显示的命令，但发生了同样的错误。

然后，我在Apple Silicon(M1)上运行Cocoapods找到了一个与官方文档https://github.com/flutter/flutter/wiki/development-with-flutter-on-Apple-Silicon相似的答案。

即使如此，堆栈溢出的答案对我来说并没有直接起作用，直到我按照以下步骤操作：

打开查找器->实用工具
右键单击终端->获取信息
选中“使用Rosetta打开”4。打开新的终端，然后键入“gem uninstall cocoapods”
sudo gem安装cocoapods 6。gem卸载FFI
arch-x86_64 sudo gem安装FFI

我希望这对别人有用。
