使用 Firebase Google Analytics SDK 构建 Unity 项目失败："Could not load file or assembly 'UnityEditor.iOS.Extensions.Xcode"

Question

问题

我正在尝试将 Firebase Google Analytics 集成到我现有的 Unity 项目（iOS 和 Android 的手机游戏）。我正在按照 https://firebase.google.com/docs/unity/setup 上的说明进行操作（所有先决条件都已满足）。不幸的是，当我尝试在 Windows 上构建 Android 版本时，出现以下错误：

我不明白为什么它会尝试加载这个程序集，它显然只用于 iOS。而且我不知道如何防止它或摆脱这个错误。

设置

• Windows 10 专业版
• 具有工作 Android/iOS 构建的现有 Unity 项目
• Unity 2019.2.16f1
• 使用 OpenJDK 和 Android SDK/NDK 与 Unity 一起打包
  • OpenJDK 1.8
  • Android SDK 工具 29.0.2
• 当前依赖项（都按预期工作）
  • Google Admob SDK for Unity
  • Unity Analytics
  • Unity IAP
  • Sentry
  • PlayMaker
• 我添加了 Google 分析，如 https://firebase.google.com/docs/unity/setup 中所述
  • 我完成了所有步骤
  • 在编辑器中执行时，将调用 CheckAndFixDependenciesAsync 延续，Firebase 依赖状态为 "Available"

构建设置

播放器设置

解决方案尝试

• 我通过Git重置了所有更改并从头开始重新执行这些步骤，重新导入SDK统一包
• 使用播放服务解析器
  • 我更新了版本处理程序
  • 我强制解决了 Android 依赖项（有效）
• 删除了 Library 文件夹并重建

不幸的是，

None 其中有帮助。如果有任何指向正确方向的指示，我将不胜感激。

Answer 1

感谢 @Cœur 的提示（感谢 1000 次）我在 Unity 编辑器中安装了 iOS 模块（尽管我只是想构建 Android 版本在 Windows 上）。安装 iOS 模块后，Android 构建工作正常。
