如何修复异常无法加载 DLL 'gdiplus.dll'：找不到指定的模块

Question

我正在 .Net Core 2.1 中开发 Service Fabric Mesh 应用程序，其中无法在 microsoft/dotnet 中使用 System.Drawing.Common：运行时（Windows 容器）

下面是我的docker文件代码

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base

WORKDIR /app

EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build

WORKDIR /src

COPY MS_Upload/MS_Upload.csproj MS_Upload/

RUN dotnet restore MS_Upload/MS_Upload.csproj

COPY . .

WORKDIR /src/MS_Upload

RUN dotnet build MS_Upload.csproj -c Release -o /app

FROM build AS publish

RUN dotnet publish MS_Upload.csproj -c Release -o /app

FROM base AS final

WORKDIR /app

COPY --from=publish /app .

ENTRYPOINT ["dotnet", "MS_Upload.dll"]

我得到的错误：

Unable to load DLL 'gdiplus.dll': The specified module could not be found.
at System.Drawing.SafeNativeMethods.Gdip.GdipCreateBitmapFromStream(IStream stream, IntPtr& bitmap)
   at System.Drawing.Bitmap..ctor(Stream stream, Boolean useIcm)

• 尝试使用 linux 容器，因为 libgdiplus 模块默认不会安装在 windows 容器上，很可能它可以正常工作

• 使用以下命令 (reference) 安装 system.Drawings 依赖项：

  运行 apt-get 更新 \ && apt-get install -y --allow-unauthenticated \ libc6-开发\ libgdiplus \ libx11-开发\ && rm -rf /var/lib/apt/lists/*

如果需要使用 windows 映像，您可以使用 chocolatey 在 windows 容器上安装这些依赖项
