When trying to run npm start, I get the error:

Error: EACCES: permission denied, open '/root/.pm2/module_conf.json'

the command in package.json looks like this

{
    "scripts": {
        "start": "pm2 start ./node_modules/laravel-echo-server/dist/index.js"
    },
    "dependencies": {
        "laravel-echo-server": "^1.6.2",
        "save": "^2.4.0"
    }
}

But if I run the command in the terminal pm2 start ./node_modules/laravel-echo-server/dist/index.js it works fine

/app # pm2 start ./node_modules/laravel-echo-server/dist/index.js
[PM2] Starting /app/node_modules/laravel-echo-server/dist/index.js in fork_mode (1 instance)
[PM2] Done.

After searching the internet for a solution to the problem, I saw a possible solution, but it didn't work for me either. This solution was to create an ecosystem.config.js file here is an example with this solution but it doesn't work either

package.json

{
    "scripts": {
        "start": "pm2 start ecosystem.config.js"
    },
    "dependencies": {
        "laravel-echo-server": "^1.6.2",
        "save": "^2.4.0"
    }
}

ecosystem.config.js

module.exports = {
    apps : [
        {
            name: "laravelEcho",
            script: "./node_modules/laravel-echo-server/dist/index.js",
            args : "start"
        }
    ]
}

Perhaps this will help when looking for the problem, I am using Docker Dockerfile

FROM node:alpine

WORKDIR /app

RUN npm install pm2:2.9.2 -g && pm2 update

EXPOSE 8888

What could be the problem?

not sure it's great to run it as root, have a look here on pm2s git repo on user access: Starting PM2 as a non-root user is broken

i think you can fix the "permission denied" with running this as su so just run sudo npm start but because i can't code in js i can't help you with the errors i'm sorry!:/ I hope i could help you anyways a little bit!!

  • by the way are you on linux or mac? Because if you're on windows you have to run it as administrator – Namechange Jul 01 '21 at 13:06
  • i used linux Ubuntu and docker about sudo, by default docker container runs as root user and unfortunately i can't use sudo command in docker – Vladyslav Chalyi Jul 01 '21 at 13:10
  • https://stackoverflow.com/questions/50639690/on-npm-install-unhandled-rejection-error-eacces-permission-denied Look here i think that can help you, there's something about `chown` – Namechange Jul 01 '21 at 13:13
  • I tried ``` /app # chown -R $(whoami) ~/.pm2 ``` and after ``` cd ~/.pm2 chown -R $(whoami) module_conf.json but it doesn't work either – Vladyslav Chalyi Jul 01 '21 at 13:25
