c# - MSBuild 未处理的异常 : The FileName property should not be a directory unless UseShellExecute is set

• docker :18.09.7
• Linux 内核:5.0.0-27
• Ubuntu:18.04.3

问题

我正在 docker 中运行一个 ASP.NET Core 项目。当我 docker-compose up 时，我得到以下信息:

Unhandled Exception: Microsoft.Build.BackEnd.NodeFailedToLaunchException: The FileName property should not be a directory unless UseShellExecute is set. ---> System.ComponentModel.Win32Exception: The FileName property should not be a directory unless UseShellExecute is set.
   at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo)

   at Microsoft.Build.CommandLine.MSBuildApp.Execute(String[] commandLine)
   at Microsoft.Build.CommandLine.MSBuildApp.Main(String[] args)

当它命中 dockerfile 中的 dotnet restore 行时，似乎会发生错误。

检查权限后，似乎docker对直接涉及的所有文件/文件夹都有读/写权限

今天早上有一些更新，这篇文章中的其他人也说他们也有。它们是否是相同的更新是未知的。但是有一些更新。 Here is my update log from the morning that this all started happening .

我的 Dockerfile 是这样的:

FROM microsoft/dotnet:2.1.403-sdk as dotnet

WORKDIR /vsdbg

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
      unzip \
    && rm -rf /var/lib/apt/lists/* \
    && curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l /vsdbg

WORKDIR /ProjA

# Install TRX -> JUnit log file converter
# https://github.com/gfoidl/trx2junit
RUN dotnet tool install -g trx2junit
RUN export PATH="$PATH:/root/.dotnet/tools"

COPY ProjA.sln .
COPY ProjA/ProjA.csproj ./ProjA/
COPY ProjA.Tests/ProjA.Tests.csproj ./ProjA.Tests/
COPY ProjB/ProjB.csproj ./ProjB/
COPY ProjC/ProjC.csproj ./ProjC/

RUN mkdir ProjA.Tests/tmp

RUN dotnet restore # ******* Error seems to happen here...

COPY . .

WORKDIR /ProjA/ProjA/

CMD ["dotnet", "run"]

我们在 Azure 上运行 Ubuntu 18.04 作为我们的 Docker 主机。 Azure 最近推出了内核版本 5.0.0-1018，这导致我们的 Linux 容器出现问题。降级到内核版本 4.18.0-1025 为我们修复了它。
