我正在尝试为可用于管道作业的自定义映像创建Dockerfile。我想在第一阶段的形象是节点和第二阶段的形象是Ubuntu的。这是我目前拥有的。当我以交互方式运行容器时，我可以使用“node”命令。但是，当我输入“npm”时，我得到以下错误：

node:internal/modules/cjs/loader:1031
  throw err;
  ^

Error: Cannot find module '../lib/cli.js'

}

字符串
以下是我在Dockerfile中使用的代码：

# Stage 1: Node.js/npm stage
FROM node:16 AS node
WORKDIR /app
# Stage 2: ubuntu stage
FROM ubuntu 

# Set the working directory in the container
WORKDIR /app

# Copy the Node.js/npm components from the Node.js/npm stage
COPY --from=node /usr/local/bin/node /usr/local/bin/
COPY --from=node /usr/local/bin/npm /usr/local/bin/

型
我希望“npm”命令返回一个npm选项列表，或者至少在输入npm --version时显示版本。
