Autostart woes

sdetweil

I see this in the pi/.pm2/pm2.log, after service pm2-pi start

internal/modules/cjs/loader.js:583
    throw err;
    ^

Error: Cannot find module './lib/eventemitter2'

and the systemctl status pm2-pi.service command produces

● pm2-pi.service - PM2 process manager
   Loaded: loaded (/etc/systemd/system/pm2-pi.service; enabled; vendor preset: enabled)

so, it looks like some pm2 install problem

I see this error/warning during

sudo npm pm2 install -g

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules/pm2/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“arm”})

i gave up on pm2, edited /etc/rc.local

@sdetweil

Did you try installing it without sudo? Just a guess

sdetweil

@mykle1 yes, cut and paste from the mm doc

I’d recommend trying to do it again using the description by MichMich
https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

It is crystal clear from what I see, also describes what to do.

"the doc for ‘pm2 startup’ doesn’t help me…
‘will give you the command u need to execute’

execute when, how? if unattended, who is ‘you’?"

No offense, but btoh the doc and your terminal will show you exactly what to do. Copy a line of text the terminal throws out and execute it again.

That’s the reason I’d suggest to do it again with a bit more patience. :-)
