Flutter IOS Cocoapods‘Cocoapods的错误输出：’

Question

我在模拟器上运行我的iOS应用程序没有问题。在我尝试实现facebook登录后，我的Flutter项目开始需要安装Cocoapods。

在安装Cocoapod之后，我尝试在iOS模拟器上使用flutter run，但是我得到了这个错误：

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running pod install...                                           2.043ms
CocoaPods' output:
      Preparing

    Analyzing dependencies

    Inspecting targets to integrate
      Using ARCHS setting to build architectures of target Pods-Runner: (``)

    Fetching external sources
    -> Fetching podspec for Flutter from Flutter
    -> Fetching podspec for flutter_facebook_auth from .symlinks/plugins/flutter_facebook_auth/ios

    Resolving dependencies of Podfile

Error output from CocoaPods:
↳

        /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.4/lib/ffi_c.bundle: mach-o, but wrong architecture -... etc

为什么我在没有安装Cocoapods的情况下可以正常运行，而今天却必须在我的Emulator上运行？现在我得到了所有这些错误！

PS:我的Podfile已经配置了plataform: ios, '9.0'，并且我在ios中没有开发人员帐户。

我找到了解决方案。

在项目路径上，打开终端并运行gem install ffi

在Podfile目录下，在终端上运行arch -x86_64 pod install或pod install
