Docker Build Problem "Error: Cannot find module"

I have a problem with the execution of the docker build command, in my Nuxt frontend docker container. This is my Dockerfile:

FROM node:lts-alpine as base

RUN npm install -g pnpm

WORKDIR /usr/src/app

COPY package.json pnpm-lock.yaml ./

RUN pnpm install

COPY . .

RUN pnpm run build
EXPOSE 3000

FROM node:lts-alpine as final
WORKDIR /app
COPY --from=base /usr/src/app/.output .

EXPOSE 3000
CMD ["node", "server/index.mjs"]

When running docker build with this Dockerfile I get the following error:

 => [base 4/7] COPY package.json pnpm-lock.yaml ./                                                                 0.1s

  1. I ran docker build with the --no-cache flag.
  2. I commented out the RUN pnpm run build line and went inside the container to check if the file exists in there. It does not.

Should this file even be in there? Has anybody had the same problem?

    I found the solution. I was missing the .dockerignore file, so my node_modules folder was copied over.

    Do you have all of the required packages listed in package.json?

    🗎 package.json

    {
  "name": "test",
  "private": true,
  "scripts": {
    "build": "nuxi build"
  },
  "engines": {
    "npm": "^9.0.0"
  },
  "dependencies": {
    "nuxt": "3.11.1",
    "nuxi": "3.11.1",
    "@nuxt/kit": "3.11.1"
  }
}

    🗎 Dockerfile (Same as the one provided in question except the EXPOSE omitted from base stage.)

    FROM node:lts-alpine as base

RUN npm install -g pnpm

WORKDIR /usr/src/app

COPY package.json pnpm-lock.yaml ./

RUN pnpm install

COPY . .

RUN pnpm run build

FROM node:lts-alpine as final

WORKDIR /app

COPY --from=base /usr/src/app/.output .

EXPOSE 3000

CMD ["node", "server/index.mjs"]
