[08.01.2023 16:24.39.770] [LOG]   config=/mnt/config.js

I added a console print to verify

i set up pm2 with a startup script which looks like this

cd ~/MagicMirror
export MM_CONFIG=/mnt/magicmirror/config.js
DISPLAY=:0 npm start

I’ve verified that the config.js is present at that folder location. when I start with pm2 i get the screen that says
“Please create a config file or check the existing one for errors”

to test if it was permissions error on the /mnt directory files. I copied the config to ~/mmconfig and edited the script to read

...
export MM_CONFIG=/home/egzachly/mmconfig/config.js
...

And I get the same error message.

I then confirmed that there is not an error with the config.js by copying it to ~/MagicMirror/config/config.js and starting with

npm start

And it runs flawlessly. Unfortunately, running it from there is not what I want to do. Is there a syntax error in my pm2 shell script?

u can set the path/name of the config.js

this also makes it so you could launch multiple instances from the same mm folder w different configs

export MM_CONFIG=full path to config file, or just name
edit MMM_CONFG_FILE is the correct env variable

search posts w mm_config to see prior discussions

this is done by the node_helper of some module

today the decision logic is in the browser side, the execution is in the helper.

so client side (browser) only doesn’t work for this
