指定的框架＆＃39; Microsoft.AspNetCore.App＆＃39;，版本＆＃39; 2.1.0＆＃39;在visual studio 7.5 mac中找不到docker

Question

我正在尝试在mac os X上的docker上运行该项目。项目已成功构建，但目标进程已退出而未引发CoreCLR启动事件。

以下是错误列表

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '2.1.0' was not found.
  - Check application dependencies and target a framework version installed at:
      /
  - Alternatively, install the framework version '2.1.0'.
The target process exited without raising a CoreCLR started event. Ensure that the target process is configured to use .NET Core. This may be expected if the target process did not run on .NET Core.The program '[14] dotnet' has exited with code 131 (0x83).

我已经添加了Microsoft.AspNetCore.App＆＃39; 2.1.0＆＃39;在每个项目中。这是该项目的屏幕截图。

Answer 1

发现解决方案需要更改docker文件

FROM microsoft/dotnet:2.1-sdk AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY MeroRentalDev.sln ./
COPY Auth.API/Auth.API.csproj Auth.API/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/Auth.API
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Auth.API.dll"]

需要将 FROM microsoft / aspnetcore AS base 更改为 FROM microsoft / dotnet：2.1-sdk AS base

你的Dockerfile＆amp; dotnet --info看起来像？

我遇到了这个问题，直到我重新安装了最新的dotnet 2.1.0 SDK，因为我没有使用多arch构建，并且仍在使用我的本地开发环境，它安装了2.1.0-rc1，并且容器本身安装了2.1.0。
