Dotnet Pack vs Nuget.exe Pack，版本降级错误

Question

我们已从使用 nuget.exe 包更改为 dotnet 包（以摆脱对 .nuspec 文件的需要）

我们曾经运行过这个命令：

    nuget pack "MyComp.Shared\MyComp.Shared.csproj" -OutputDirectory c:\nugetlocal -version 2021.7.7.1149-local -symbols

在开发过程中，我们在本地项目中使用这个打包好的 nuget 不会有任何问题。

现在我们运行

    dotnet pack "MyComp.Shared\MyComp.Shared.csproj" -output c:\nugetlocal -version 2021.7.7.1149-local --include-symbols

但是，当我们使用这个包时，我们现在会遇到版本降级错误。使用第一个命令打包 nuget.exe 时不会发生这种情况。

编辑：this 链接确实有助于解决问题

要了解问题，

您可以获取一个 .nupkg 文件，将扩展名更改为 .zip，然后打开该文件。里面是一个 .nuspec 文件。

当我们使用 nuget.exe 打包时，<dependancies /> 标记中不包含任何内容。

我们意识到 dotnet pack 获取项目引用会将它们添加到内部 .nuspec 文件中，并使用与您正在打包的项目相同的版本号标记它们

所以我们需要确保在构建一个时，我们会构建依赖项并使用它们。
