我试图建立一个IOSFlutter项目，但它是不断抱怨的兼容版本的pod。我已经尝试了许多线程，因为过去两天，但无法解决这个问题。不过我的Android版本运行良好。
我尝试删除podfile.lock，podfile，podfolder，Runner.xcworkspace，但没有任何效果。现在我不再拥有podfile.lock文件了。我的意思是podfile.lock没有被创建。
macOS Big Sur版本11.6
MacBook Pro 2019
处理器：2.3 GHz Intel Core i9
在我的Podfile中：

platform :ios, '10.0'

我还尝试了以下命令：

sudo arch -x86_64 gem install ffi

   arch -x86_64 pod install

运行pod install命令时，出现以下错误。

我也试过this线程，但不为我工作...
任何帮助将不胜感激。。
