macos - 错误 MSB4057 : The target "Pack" does not exist in the project - Visual Studio for Mac

Question

我有一个项目 https://github.com/PandaWood/Simple-MAPI.NET

我一直使用Build |创建 Nuget 包 - 始终有效 - 创建一个 nuget 包。

我在 Visual Studio for Mac 上构建它(使用 Mono)

截至今天(假设 Visual Studio 中的更新导致了此问题)- 我收到上述错误(目标“Pack”不存在”)

我认为这是一个错误，因为自从它起作用以来我没有更改任何代码或配置。

关于如何让它再次运行有什么建议吗？ 在这种情况下，该错误对我来说毫无意义

问题是项目文件中 NuGet.Build.Packaging.props 和 NuGet.Build.Packaging.targets 的导入不正确。当前导入指向 src/Mapi/packages 目录。

<Import Project="packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.props" Condition="Exists('packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.props')" />

<Import Project="packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.targets" Condition="Exists('packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.targets')" />

您的解决方案位于 GitHub 存储库的根目录，因此包将在那里恢复，而不是在 Mapi 文件夹中。因此，按如下方式更改路径应该可以解决 Pack 目标不可用的问题:

<Import Project="..\..\packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.props" Condition="Exists('..\..\packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.props')" />

<Import Project="..\..\packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.targets" Condition="Exists('..\..\packages\NuGet.Build.Packaging.0.1.248\build\NuGet.Build.Packaging.targets')" />
