Question

I'm using below package.json in my node project and when i run npm test, it gives the below error

Module version mismatch. Expected 48, got 51

{
  "name": "f-api",
  "version": "0.0.1",
  "Description": "F",
  "author": "F",
  "private": true,
  "scripts": {
    "start": "node ./bin/www",
    "start_supervise": "supervisor ./bin/www",
    "test": "mocha --recursive --timeout 10000"
  },
  "dependencies": {
    "bcrypt": "=1.0.2",
    "body-parser": "~1.13.2",
    "config": "^1.24.0",
    "cookie-parser": "~1.3.5",
    "debug": "~2.2.0",
    "express": "~4.13.1",
    "jwt-simple": "^0.5.1",
    "moment": "^2.17.1",
    "morgan": "~1.6.1",
    "nodemailer": "=2.7.2",
    "nodemailer-smtp-transport": "^2.7.2",
    "pg-promise": "^3.2.3",
    "sequelize": "^3.29.0",
    "sequelize-cli": "^2.1.0",
    "supervisor": "^0.12.0"
  },
  "devDependencies": {
    "chai": "^3.5.0",
    "chai-http": "^3.0.0",
    "mocha": "^3.2.0",
    "nodemailer-stub": "^1.0.1",
    "should": "^11.1.2",
    "supertest": "^2.0.1"
  }
}

I think it's some incompatibility of versions, i'm bit new to node, npm and versions syntax like ^, ~, =

How are you running the process?

If it might help anyone, we had a similar issues running node via pm2, we were getting this error: Error: Module version mismatch. Expected 48, got 57

It seems the number refers to NODE MODULE version, 48 is node 6, 57 is node 8.

We were running our pm2 processes and each process specifies a particular node version to use. They were point to node 6 versions, even thought our current nvm use version was at 8.12. (node.js version 8.12.0 )

Deleting and restarting the PM2 jobs, created the tasks with the updated link to node 8.12 and we stopped getting that error.

Hope it helps someone!
