我正在创建一个Dockerfile来构建和部署ASP.NET 4应用程序。我有这段代码：
#Use the add-msbuild image that has msbuild.exe installed. This image inherits from microsoft/iis.
FROM add-msbuild
#Make a folder in the container that will contain the application.
RUN mkdir "C:\site"
RUN mkdir "C:\site\packages"
RUN mkdir "C:\build"
#Copy the application source code to the build folder.
COPY . "C:\build"
WORKDIR "C:\build"
#Build the application.
RUN ["nuget.exe", "restore"]
RUN ["C:\\Program Files (x86)\\MSBuild\\12.0\\Bin\\msbuild.exe", "C:\\build\\*.csproj"]
我创建了另一个名为add-msbuild的图像，它继承自microsoft / iis。这样，我有一个安装了msbuild和nuget的映像，这样我就可以构建我的代码了。此dockerfile从包含源代码的文件夹运行。
问题：我无法使RUN ["nuget.exe", "restore"]行生效。 CLI给出了这个错误：Cannot determine the packages folder to restore NuGet packages. Please specify either -PackagesDirectory or -SolutionDirectory.
好的，好的。我将添加此参数。我尝试了以下方法：
RUN ["nuget.exe", "restore", "PackagesDirectory"]
RUN ["nuget.exe", "restore", "-PackagesDirectory 'C:\site\packages'"]
RUN ["nuget.exe", "restore", "PackagesDirectory 'C:\site\packages'"]
RUN ["nuget.exe", "restore", "PackagesDirectory", "C:\site\packages"]
RUN ["nuget.exe", "restore", "-PackagesDirectory", "C:\site\packages"]
但是所有方式都会给出错误信息。我究竟做错了什么？如果有任何不同，我会使用docker build -t myproject .开始构建。
编辑：从C:\build文件夹运行ls命令会返回：
