错误：找不到模块 '/next'、docker、next.js

Question

I want to create containers out of my next.js application however I encounter a weird error that I couldn't solve after about 3 days of investigating.

package.json:

{
  "name": "client",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "dev": "next",
  },
  "keywords": [],
  "author": "Shahin Ghasemi",
  "license": "ISC",
  "dependencies": {
    "next": "^9.4.4",
    "react": "^16.13.1",
    "react-dom": "^16.13.1"
  }
}

Dockerfile:

FROM node:alpine
COPY package.json .
RUN npm install
CMD [ "next", "run","dev" ]

When I run the command docker build -tx/y:tag. it creates the image successfully. however, when I want to run the container it gives me this error:

$ docker run  abbe27e7cc4d
internal/modules/cjs/loader.js:1023
  throw err;
  ^

Answer 1

You could try

CMD [ "npm", "run", "dev" ]

Hope this helps.

-Try turning off your antivirus (sometimes it blocks normal package updates); -Check the changes in package.json; -npm update -npm audit fix
