C# 指定的框架'；Microsoft.AspNetCore.All'；，版本'；2.1.2'；找不到

我创建了我的应用程序，它成功地创建了docker容器。当我试着运行它的时候

docker run -it --name myapp myapp:latest

我得到以下错误：

The specified framework 'Microsoft.AspNetCore.All', version '2.1.2' was not found.
...
- The following versions are installed:
      2.1.1 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.All]

当我登录到容器中时，我可以看到，在

/usr/share/dotnet/shared/Microsoft.AspNetCore.All

文件夹中，有一个子文件夹名为

2.1.2

我不明白为什么它说2.1.1已经安装，而2.1.2没有安装

以下是我的Dockerfile：

FROM microsoft/dotnet:2.1.400-sdk-stretch AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1.400-sdk-stretch AS build
WORKDIR /src
COPY source/application/MyApp/MyApp.csproj source/application/MyApp/
COPY source/application/MyApp.DependentProject/MyApp.DependentProject.csproj source/application/MyApp/
RUN dotnet restore source/application/MyApp/MyApp.csproj
COPY . .
WORKDIR /src/source/application/MyApp
RUN dotnet build MyApp.csproj -c Release -o /app

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

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

您可以尝试更改：

FROM microsoft/dotnet:2.1.400-sdk-stretch AS base

到

或

您使用的docker容器映像是什么？我正在尝试列出的各种映像。我使用microsoft/dotnet:2.1.400-sdk-stretch作为基础。我不确定是否相关，但docker支持是在事实发生后添加的，第一次创建项目时不在项目模板中。从microsoft/dotnet AS base创建相同的结果，即安装了2.1.1，但未安装2.1.2。docker文档中有此步骤，例如#从microsoft/dotnet生成运行时映像：aspnetcore runtime WORKDIR/app COPY--FROM=Build env/app/out。入口点[“dotnet”，“aspnetapp.dll”]

FROM microsoft/dotnet AS base

FROM microsoft/dotnet:2.1.2-sdk AS base
