无法在 Mac 上为 iOS 运行 Uno 项目 - 无法加载 `SQLitePCLRaw.core`

Question

我有一个 UWP 应用程序，我使用 Uno 平台移植到 iOS & Android。我可以在 Windows 上构建运行 iOS 项目，但是当我尝试在 Mac 上构建运行项目时，出现以下错误：

Error: System.TypeLoadException: Could not load type of field 'Microsoft.CodeAnalysis.SQLite.Interop.SqlConnection:_handle' (0) due to: Could not load file or assembly 'SQLitePCLRaw.core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1488e028ca7ab535' or one of its dependencies.

即使我添加了对此包的引用，错误仍然存在并且我无法运行该项目。完整的堆栈跟踪如下：

我使用的是 Uno.Platform 的最新发布版本（未预发布）：

  <package id="Uno.CodeGen" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Core" version="1.25.0" targetFramework="xamarinios10" />
  <package id="Uno.Core.Build" version="1.25.0" targetFramework="xamarinios10" />
  <package id="Uno.Equality" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Immutables" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.Injectable" version="1.29.0" targetFramework="xamarinios10" />
  <package id="Uno.SourceGenerationTasks" version="1.28.0" targetFramework="xamarinios10" />
  <package id="Uno.UI" version="1.42.0" targetFramework="xamarinios10" />

是否可以运行 iOS 应用程序，使用 Uno 平台在 Mac 上开发？

Answer 1

正如安德烈斯所提到的，这已在最新的开发中得到修复。如果需要，您可以在我们的 Gitter 频道上获得更多帮助：https://gitter.im/uno-platform/Lobby#

Answer 2

我尝试将 Uno.UI 软件包更新到最新的预发布版 - 但没有帮助。我不仅要更新 Uno.UI 包，还要手动更新所有未使用 Uno.UI:

拉取的相关包

  <package id="Uno.CodeGen" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Core" version="1.26.0-dev.61" targetFramework="xamarinios10" />
  <package id="Uno.Core.Build" version="1.26.0-dev.61" targetFramework="xamarinios10" />
  <package id="Uno.Equality" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Immutables" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Injectable" version="1.30.0-dev.107" targetFramework="xamarinios10" />
  <package id="Uno.Roslyn" version="1.2.0-dev.18" targetFramework="xamarinios10" />
  <package id="Uno.SourceGenerationTasks" version="1.29.0-dev.226" targetFramework="xamarinios10" />
  <package id="Uno.UI" version="1.43.0-dev.614" targetFramework="xamarinios10" />

这个软件包列表工作正常。
