node.js - node,js 在官方 node.js docker 镜像上找不到本地安装的模块

Question

即使模块目录是正在执行 npm 的子目录，node.js 似乎也无法找到本地安装的模块。我确实观察到发现全局安装的模块没有问题。我确实查看了这个 docker 图像的 Git 文档，但我没有发现任何表明我做错了什么的东西。 https://github.com/nodejs/docker-node/blob/main/README.md#how-to-use-this-image

以下是使用的文件和生成的日志。

更新找到的解决方案

谢谢大卫迷宫的帮助。

基本上，当我堆积 docker 卷时，我正在覆盖工作目录。在 Daivd 的帮助下，我发现您可以通过在初始卷挂载后添加额外的 docker 卷来重新加载现有的子目录。例如...

你可以挂载包含node.js代码的目录
-v /home/docker/node-app:/home/node/app

然后你可以挂载构建docker镜像时创建的node_modules目录在你挂载你的 node.js 代码之后。
-v /home/node/app/node_modules

这解决了我的问题。

Dockerfile

FROM node:14
WORKDIR /home/node/app
EXPOSE 3000
COPY package.json /home/node/app
RUN npm install
CMD ["npm", "start"]
