ios - Flutter IOS Cocoapods 'Error output from Cocoapods:'

Question

我在模拟器上运行我的 iOS 应用没有问题。在我尝试实现 facebook 登录后，我的 Flutter 项目开始要求安装 Cocoapods。

安装 Cocoapod 后，我尝试在 iOS 模拟器上 flutter run，但出现此错误:

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

为什么我没有安装这个 Cocoapods 就可以正常运行，今天却需要在我的 Emulator 上运行？现在我遇到了所有这些错误!

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

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 目录上运行 arch -x86_64 pod install 或在终端上运行 pod install
