Azure 构建管道 NuGet 还原错误 NETSDK1045

Question

我通过 Visual Studio 2019 创建了一个 Azure CI 管道。项目目标框架是 .net core 3.1。但是，在 NuGet 还原期间它会失败。 我的计算机上安装了 .Net Core 2.2.2017 和 3.1.101，我的 Visual Studio 2019 社区版本是 16.4。我的环境变量路径已经到位。

我还尝试手动创建一个使用 .net core 3.1 LTS 堆栈的应用服务，但我仍然遇到同样的错误。

    ##[error]The nuget command failed with exit code(1) and error(C:\Program Files\dotnet\sdk\2.2.110\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(137,5):

    error NETSDK1045: The current .NET SDK does not support targeting .NET Core 3.1.  Either target .NET Core 2.2 or lower, or use a version of the .NET SDK that supports .NET Core 3.1. 

这是 Visual Studio 生成的 YAML 文件

Answer 1

我相信，你不需要安装 NuGetToolInstaller 和 vsbuild，你应该先安装 DotNetCoreCLI 之后你可以使用它. Here is manual你的 yaml 文件应该是什么样子。

Answer 2

通过 IDE 发布没有痛苦，因为它使用您在机器上安装的工具，在管道中您需要指定要使用的工具，这就是痛苦。

对于那些不使用基于 YAML 的新管道而是在 devops 上使用经典编辑器的用户，您可能需要添加 dot net core add task 并将 nuget restore 更改为 dotnet restore task

Answer 3

当我从 Azure Devops UI 创建管道时，我的 YAML 如下所示。它使用DotNetCoreCLI 而不是VSBuild。请注意，它使用Restore 命令，而不是与 Nuget 相关的任何内容。
