我有一个由 .NET 6 和 React 开发的项目，当我在本地发布它时可以成功运行，但是当我使用 Dockerfile 时它会出现此错误：

我认为容器中没有安装节点。不过，我在 docker 文件中添加了安装代码：
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
RUN apt-get update -yq && apt-get upgrade -yq && apt-get install -yq curl git nano
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - && apt-get install -yq nodejs build-essential
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["psreactnet.csproj", "."]
RUN dotnet restore "./psreactnet.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "psreactnet.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "psreactnet.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "psreactnet.dll"]
如何在容器中安装node？
发布阶段没有基础阶段。尝试在构建阶段安装节点
尝试在“as build”阶段之后添加 RUN apt-get... 和 RUN curl -sL de...
#base stage
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
...
#build stage
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
RUN apt-get update -yq && apt-get upgrade -yq && apt-get install -yq curl git nano
RUN curl -sL https://deb.nodesource.com/setup_16.x | bash - && apt-get install -yq nodejs build-essential
WORKDIR /src
...
由于 NodeSource 设置脚本现已弃用，以下是在 Dockerfile 中使用
apt-getFROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
...
# Install NodeJS
RUN apt-get update && \
apt-get install -y ca-certificates curl gnupg && \
mkdir -p /etc/apt/keyrings && \
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
ARG NODE_MAJOR=20
RUN echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | tee /etc/apt/sources.list.d/nodesource.list && \
apt-get update && \
apt-get install nodejs -y
...
主要命令基于https://github.com/nodesource/distributions#installation-instructions
的安装文档或者，您可以使用已包含两者的图像。这显着降低了 docker 映像的构建时间，因为无需安装节点及其依赖项。
这是一个使用 .NET 6 和节点 v18 的示例
#base stage
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
...
#build stage
FROM dotnetimages/microsoft-dotnet-core-sdk-nodejs:6.0_18.x AS build
WORKDIR /src
