构建服务器上的 dotnet restore 表示软件包与“net50”不兼容

Question

我有一个 .NET 5 解决方案，可以在多台机器上正常构建，但在 TeamCity 构建服务器上却没有。

C:\redacted.WebAPI.csproj : error NU1202:   - net5.0 (.NETCoreApp,Version=v5.0)
C:\redacted.WebAPI.csproj : error NU1202:   - netcoreapp3.1 (.NETCoreApp,Version=v3.1)

C:\redacted.IntegrationTests.csproj : error NU1202:   - netcoreapp3.1 (.NETCoreApp,Version=v3.1)

所有项目都有 <TargetFramework>net5.0</TargetFramework>。

构建服务器上的

dotnet 版本是 5.0.300，在 Windows Server 2012 R2 上。 VC++ 构建工具也已更新 (MSBuild version = "16.10.0+4242f381a")。

这里有什么线索吗？我准备拔头发了。

Answer 1

发现问题。从详细日志来看，dotnet restore 似乎使用 3.1 SDK 进行包恢复，即使它是从 5.0 SDK 开始的。

原来定义了一个环境变量 MSBuildSDKsPath，它指向 2.1 SDK。将其设置为 5.0 SDK 后，恢复工作正常。

由您的 CI 服务器引起的问题，而不是由 dotnet 或 .NET SDK 引起的。
