解决步骤 #

1. 检查NuGet源配置 #

打开Visual Studio 2019，依次点击工具 > NuGet包管理器 > 包管理器设置，在弹出窗口中选择包源，确认已添加官方NuGet源（https://api.nuget.org/v3/index.json）。若未添加，点击加号新增该源并命名为nuget.org。

2. 自动还原NuGet包 #

打开项目对应的Windows解决方案文件（.sln），在Visual Studio中右键点击解决方案，选择还原NuGet包。等待还原完成后，重新执行npx react-native run-windows。

3. 手动安装缺失包 #

若自动还原失败，通过NuGet包控制台手动安装每个缺失包：

• 打开工具 > NuGet包管理器 > 包管理器控制台
• 依次执行以下命令：

Install-Package Microsoft.UI.Xaml -Version 2.3.191129002
Install-Package Microsoft.SourceLink.GitHub -Version 1.0.0
Install-Package Microsoft.Build.Tasks.Git -Version 1.0.0
Install-Package boost -Version 1.72.0
Install-Package Microsoft.WinUI -Version 3.0.0-preview2.200713.0
Install-Package Microsoft.SourceLink.Common -Version 1.0.0

4. 清理重建项目 #

若上述步骤无效，尝试清理后重建项目：

• 在Visual Studio中点击生成 > 清理解决方案
• 再点击生成 > 重建解决方案
• 重新执行npx react-native run-windows

5. 更新React Native Windows版本 #

部分旧版本的React Native Windows可能依赖特定版本NuGet包，若所有方法无效，尝试更新到稳定版本：

npx react-native-windows-init --overwrite
