Mac上的Visual Studio与docker有很多错误让人感到沮丧 . 我，在asp.net core 2.1上有一个项目，在docker镜像上有角度6 . 当项目成功构建但无法在下面运行时，详细信息如下：

An unhandled exception occurred while processing the request. AggregateException: One or more errors occurred. (One or more errors occurred. (Failed to start 'npm'. To resolve this:. 1 Ensure that 'npm' is installed and can be found in one of the PATH directories. Current PATH enviroment variable is: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Make sure the executable is in one of those directories, or update your PATH. 2 See the InnerException for further details of the cause.)) System.Threading.Tasks.Task.GetResultCore(bool waitCompletionNotification) InvalidOperationException: Failed to start 'npm'.

info for details

added more image

services.AddNodeServices(options =>
            {
                options.ProjectPath = "/Library/Frameworks/Mono.framework/Commands:/Applications/Visual Studio.app/Contents/Resources:/Applications/Visual Studio.app/Contents/MacOS:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:/usr/local/bin/";
            });

这是docker文件信息

FROM microsoft/dotnet:2.1-sdk AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY MeroRentalDev.sln ./
COPY WebApp/WebApp.csproj WebApp/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/WebApp
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "WebApp.dll"]

    最后解决这个问题 . 这个问题是由于node.js没有安装在asp.net core 2.1 docker镜像上 .

    因此，在docker容器中安装节点js

    # Setup NodeJs
RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y gnupg2 && \
    wget -qO- https://deb.nodesource.com/setup_8.x | bash - && \
    apt-get install -y build-essential nodejs
# End setup

    在修改和更改节点版本值之前，请检查节点的版本 . 在我的情况下，我有8.11.3所以 setup_8.x

    完整的docker文件

    FROM microsoft/dotnet:2.1-sdk AS base

    # Setup NodeJs
    RUN apt-get update && \
        apt-get install -y wget && \
        apt-get install -y gnupg2 && \
        wget -qO- https://deb.nodesource.com/setup_8.x | bash - && \
        apt-get install -y build-essential nodejs
    # End setup
    WORKDIR /app
    EXPOSE 80

    FROM microsoft/dotnet:2.1-sdk AS build
    WORKDIR /src
    COPY MeroRentalDev.sln ./
    COPY WebApp/WebApp.csproj WebApp/
    RUN dotnet restore -nowarn:msb3202,nu1503
    COPY . .
    WORKDIR /src/WebApp
    RUN dotnet build -c Release -o /app

    FROM build AS publish
    RUN dotnet publish -c Release -o /app

    FROM base AS final
    WORKDIR /app
    COPY --from=publish /app .
    ENTRYPOINT ["dotnet", "WebApp.dll"]
