系统聚合异常：无法启动节点进程

Question

我已经使用vs2017在mac os中创建了一个角度应用程序，并在示例表单Creating a new Angular project on Mac with Visual Studio之后使用docker支持三个项目。由于其他项目是Web API。由于其他项目在docker上成功运行。但是只有角度应用程序没有运行，它会抛出错误，如下所示

System.AggregateException: "One or more errors occurred. (Failed to start Node process.

修改了角度app docker文件

更改此行

FROM microsoft/aspnetcore:2.0 AS base

到

FROM microsoft/aspnetcore-build:2.0 AS base

更新了Docker文件

FROM microsoft/aspnetcore-build:2.0 AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:2.0 AS build
WORKDIR /src
COPY MeroRental.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"]
