错误:找不到任何已安装的.NET Core SDK [英] Error: It was not possible to find any installed .NET Core SDKs

问题描述

当我运行命令 docker run -i -t myProject 时，它显示错误:

When I run the command docker run -i -t myProject it shows error:

找不到任何已安装的.NET Core SDK您是要运行.NET Core SDK命令吗?从以下位置安装.NET Core SDK: https://aka.ms/dotnet-download

但是，我确实安装了.NET Core SDK，并且 PATH 是正确的(其后为:

However, I do have the .NET Core SDK installed and the PATH is correct (followed here: https://docs.microsoft.com/en-us/aspnet/core/test/troubleshoot?view=aspnetcore-3.1#no-net-core-sdks-were-detected).

此外，我的项目仅需要运行时.NET Core SDK.

What's more, my project only needs runtime .NET Core SDK.

有人知道可能是什么问题吗?

Does anyone know what might be the issue?

运行dotnet --info时，我得到了:

When running dotnet --info I got:

推荐答案

对我来说，发生在我的 DOCKERFILE

For me it happened when I had wrong ENTRYPOINT in my DOCKERFILE

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "SampleAppForDocker.dll"]

确保在 ENTRYPOINT 中运行正确的dll.我的 dll 文件名错误.

Make sure that you run correct dll in your ENTRYPOINT. I had wrong name of dll file.
