之前在 Ubuntu 16.04 上遇到过使用 System.Drawing.Common 的问题（博问链接），而这次是在 docker 容器中遇到了，报错信息与之前不一样，这次的错误是：
Unable to load shared library 'libdl' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibdl: cannot open shared object file: No such file or directory at Interop.Libdl.dlopen(String fileName, Int32 flag) at System.Drawing.SafeNativeMethods.Gdip.LoadNativeLibrary() at System.Drawing.SafeNativeMethods.Gdip..cctor()
容器镜像用的是 microsoft/dotnet:2.1-aspnetcore-runtime ，容器中已经安装了 libgdiplus
RUN apt-get update RUN apt-get install -y libgdiplus RUN cd /usr/lib && ln -s libgdiplus.so gdiplus.dll
请问如何解决？
