c# - "It was not possible to find any compatible framework version"与 ASP.NET Core 2.2

Question

我有一个 ASP.Net Core MVC 2.2 应用程序。 在 Visual Studio 中运行应用程序工作正常。但是，当我尝试使用 dotnet publish 发布应用程序时，出现以下错误:

It was not possible to find any compatible framework version
  The specified framework 'Microsoft.NETCore.App', version '1.0.0' was not found.
    - Check application dependencies and target a framework version installed at:
        C:\Program Files\dotnet\
    - Installing .NET Core prerequisites might help resolve this problem:
        https://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
    - The .NET Core framework and SDK can be installed from:
        https://aka.ms/dotnet-download
    - The following versions are installed:
        2.0.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
        2.1.5 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
        2.1.6 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
        2.1.7 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
        2.1.8 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
        2.1.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

        2.2.3 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

我不明白哪里可以引用 V 1.0.0，这里是 dotnet --info 的输出

Answer 1

我认为问题出在您的 PrepublishScript (dotnet bundle)。包裹BundlerMinifier.Core (版本 2.9.406)依赖于:

• .NETCoreApp1.0
• .NETCoreApp2.0
• .NETFramework4.5.2
• .NETStandard2.0

似乎因为该项目以 netcoreapp2.2 为目标，所以此引用失败并且实际上退回到 netcoreapp1.0 或只是给出误导性消息。为了完整性检查，也许将项目降级到 netcoreapp2.0 以验证它是否有效。

请注意，netcoreapp2.2 实现了 netstandard2.0，所以我希望这一切都能正常工作，但有可能在依赖期间没有发生推断分辨率。
