.NET Core2.0身份服务器+ MVC在MacOS上的构建失败

Question

我正在尝试将一个.NET核心2.0应用程序(使用身份服务器4的MVC应用程序)从MacOS上进行Docker化。我无法找到有关此错误消息的任何信息：

MacBook-Pro-3:myproject myuser$ sudo docker build -t mycompany/myproject .

The command '/bin/sh -c dotnet restore' returned a non-zero code: 1

这个应用程序在我的机器上构建和运行良好(在docker之外)--只有在运行“/myproject”时才会出现这种情况。

这是我的Dockerfile：

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "aspnetapp.dll"]

如果这有帮助，下面是web应用程序的.csproj文件：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <UserSecretsId>some-guid-000-0000-0000-00</UserSecretsId>

  </ItemGroup>

  <ItemGroup>
    <Folder Include="Scripts\view\" />
    <Folder Include="Scripts\view\home\" />
  </ItemGroup>

</Project>

UPDATE：我还尝试在Dockerfile中使用这个构建目标：

FROM microsoft/dotnet:latest AS build-env

初始错误消失了，但是在相同的构建步骤上出现了新的问题：

Answer 1

我在我公司的生产环境中犯了这个错误。与安装的.Net核心的多个版本以及与.Net标准版本不匹配有关。

在您的计算机中，它可以工作，因为它使用的是正确的版本，因为当您安装.Net Core时，最新的版本被设置为默认版本。

但是在您的解决方案中，它指向另一个包版本。作为解决办法，你可以做的是：

1. 转到部署文件夹
2. 使用类似于System.Security.Cryptography.Primitives.dll的工具打开多特派

​

1. 在您的bindredirect中使用web.config指向右的newVersion

您还可以更新从解决方案到与核心版本匹配的正确.Net标准版本的每个包。
