PM2 MagicMirror - not working

  • when i put pm2 start MagicMirror - it looks like it started the pm2 sequence, but the MagicMirror never starts:

    pi@raspberrypi:~ $ pm2 list
    │ Name        │ id │ mode │ status │ ↺   │ cpu │ memory    │
    │ MagicMirror │ 0  │ fork │ online │ 182 │ 0%  │ 20.0 MB   │
     Use `pm2 show ` to get more details about an app
    pi@raspberrypi:~ $ pm2 stop MagicMirror
    [PM2] Applying action stopProcessId on app [MagicMirror](ids: 0)
    [PM2] [MagicMirror](0) ✓

    │ MagicMirror │ 0  │ fork │ stopped │ 184 │ 0%  │ 0 B    │
     Use `pm2 show ` to get more details about an app

    I tried looking at the one that said pm2 issues, but I’m struggling to interpret into my issue (also they could be different).

    So basically this worked earlier today, and than all of a sudden I changed my time on my clock of the raspberry pi, and it no longer works after reboot. I’m sure I did something, but I don’t know what.

  • @stalker401 ok. Someone reported a similar problem after updating to latest mm version.

    They did not run

    npm install

    From the MagicMirror folder
    And any modules that have a package.json file

  • Project Sponsor

    @sdetweil I am just wondering, are the guys running Raspbian updating to the latest version before updating to 2.8? I did the Raspbian update and and then updated the MM to 2.8, did the npm install in all the modules with a package.json and no issues.

  • @mumblebaj no idea. So just experience trouble. Mostly cause they haven’t learned the ins and outs of all this.

    I’m hoping my new update script will help

  • @stalker401 actually, i’ve seen this before…

    maybe you DID run npm install in a module folder that does NOT have a package.json file.

    erase the node_modules folder in that module

    cd modules/????   ??? is the module name
    rm -rf node_modules
