pm2 Unexpected token import

问题

I have a webserver that works when I use node or nodemon (e.g. "nodemon index.js"). However, when I try to use pm2 ("pm2 start index.js"), I get "SyntaxError: Unexpected token import". The full error log is below. What am I doing wrong here?

/usr/local/lib/node_modules/pm2/lib/ProcessContainerFork.js:29
import(process.env.pm_exec_path);
^^^^^^

Hit the same issue.

pm2 released version 4.2.2 which only works with Node 10.x or better, so:

Best solution is to upgrade your node from 9.x to 10.x or better.

In my case I wanted to stick to node 9 so I fixed the version of pm2 to version 4.2.1

I use npm to install pm2 in my Dockerfile:

Changing:

RUN npm install -g webpack@4.29.3 pm2

To:

RUN npm install -g webpack@4.29.3 pm2@4.2.1

Will fix the issue and allow you to continue working with node 9 and pm2 4.2.1

If you install pm2 in some other way post your install details and I can recommend how to fix.

After upgrading node to v12 (and reinstalling pm2) it seems like pm2 was trying to run my services using the old configuration it had saved. All I had to do was delete and start them fresh.

pm2 delete <app-name>
pm2 start src/app.js --name="<app-name>"

For the latest pm2,u need to create an ecosystem.config.js file,the content is like

module.exports = {
  apps : [{
    name: "mp-todo",
    script: "./build/index.js",
    env: {
      NODE_ENV: "development",
    },
    env_production: {
      NODE_ENV: "production",
    },
    log_date_format: 'YYYY-MM-DD HH:mm Z',
    combine_logs: true
  }]
}

and u can use pm2 start ecosystem.config.js --env production to use the environment variables in the config file
