c# - gitlab CI 中的 ASP.NET 核心项目构建错误：错误 NETSDK1045：当前的 .NET SDK 不支持针对 .NET Core 5.0

Question

当我使用这个 CI 配置文件时，从 gitlab 管道获取构建错误：

/usr/share/dotnet/sdk/2.1.809/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.TargetFrameworkInference.targets(137,5)：错误NETSDK1045：当前的.NET SDK不支持定位.NET核心 5.0。以 .NET Core 2.1 或更低版本为目标，或者使用支持 .NET Core 5.0 的 .NET SDK 版本。

variables:
    # 1) Name of directory where restore and build objects are stored.
    OBJECTS_DIRECTORY: 'obj'
    # 2) Name of directory used for keeping restored dependencies.

    # 3) A relative path to the source code from project repository root.

    SOURCE_CODE_PATH: '*/*/'

# ### Define stage list

stages:

    paths:
    # Specify three paths that should be cached:

    # frameworks etc. It also holds information where to the dependencies were restored.

    # 2) Other NuGet and MSBuild related files. Also needed.
    - '$SOURCE_CODE_PATH$OBJECTS_DIRECTORY/*.csproj.nuget.*'
    # 3) Path to the directory where restored dependencies are kept.
    - '$NUGET_PACKAGES_DIRECTORY'
    
    # 'pull-push' policy is the default cache policy, you do not have to specify it explicitly.

# ### Restore project dependencies
before_script:
    - 'dotnet restore --packages $NUGET_PACKAGES_DIRECTORY'

我们应该准确地编写 dotnet 版本：

利用
