ASP.NET Core 2.2 “不可能找到任何兼容的框架版本”

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]

        2.2.3 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

我认为问题出在你的PrepublishScript（dotnet bundle）上。该软件包BundlerMinifier.Core（版本 2.9.406）依赖于：

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

看来自从项目目标以来netcoreapp2.2，这个参考文献就失败了，要么实际上回落到了netcoreapp1.0，要么只是给出了误导性的信息。为了进行健全性检查，也许可以将项目降级以netcoreapp2.0验证其是否有效。

只是注意，netcoreapp2.2implements netstandard2.0，所以我希望这一切都有效，但有可能在依赖解析期间没有发生推理。
