[ERROR] _ is not defined

Hi,
I have an issue, appeared after MMM-SolarPicture installation but I don’t think it’s related to it. Maybe an error on my configuration.pm2 logs is this one below

thank you for your help

@sdetweil
Sam… I don’t know how to saying it.
I figure out the issue.After your last message I tried what you suggest.
With the default cfg I had no errors, with mine I had errors.So I checked again and again the config…
and I find an underscore _ right at the start of the confignpm config:check told me “no syntax errors” and that confusing me.
When I edit it I use nano editor
I do “sudo nano config.js” and I press CTRL + _ to jump at the 250 line.
Might be one of the latest time I opened it and press _ a bit faster than CTRL and I add it for error.In addition I notice that when I open config.js with nano editor the green cursor is, clearly, at the start of the first line… EXACTLY on the undescore _ and it hides it.
I’m really sorry for bothering you with that.
How can I buy you a coffee ?
Thanks -
@nowayto >Node.js v20.18.1
2.31.0 requires node 22.14 or above
how did you get here?
also you are on 2.31.0-develop
so you had a temp fix
and didn’t read the post i put outhttps://forum.magicmirror.builders/topic/19561/version-2.31.0-april-1-2025-upgrade-reminder
-
@sdetweil I didn’t update MM since I’ve installed it months ago, so I suppose it wasn’t that. Might be it updated automatically?
I remember you told me to use a “temp fix” to solve a problem.
Now I’ll follow your guide in the post to update it.
Thanks -
@sdetweil Do you suggest to update manually or auto? Thanks
-
@nowayto i never suggest update automatically.
use my script -
@sdetweil I’m sorry for the question: that script?
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)”
Thanks
-
@nowayto yes, but its two steps
one time without any parameters (test mode)
and one time with applyall you have to do is click/copy the first time and run it
then do the same on the second if the first ends successfully -
@sdetweil MM doesn’t work.
I tried a config check but I have this error now.
I tried to “npm install eslint -g” but the error persistnpm run config:check

If it can help I had first problem after the MMM-SolarPicture
but I’ve just installed it and configured it through config.js… nothing more than usual…but the actual behaviour is that pm2 status says it’s running, but on the monitor I see just the raspbian desktop

@nowayto two things
doing test run = true, NO updates will be applied!
upgrading from version 2.31.0 to 2.31.0doing test run changes nothing, its a safety check
and i wont let you upgrade over the same release accidentally
so you need to rerun the command and add
forceto the end
-
@nowayto NEVER use sudo with any npm command
the number in the pm2 status 4311 is the number of restarts
youve got a mess
now we HAVE to use sudo to undo it
cd ~/MagicMirror sudo rm -rf node_modules cd fonts sudo rm -rf node_modules cd ..\vendor sudo rm-rf node_modules cd ..lets see about node
which node n q to quit nvmdont do anything else til we figure out the nodejs problem
-
@sdetweil I’m sorry :(
I did it what you suggest and config:check gave me a module error again. Different than one before
npm run config:check
magicmirror@2.31.0 config:check
node js/check_config.jsnode:internal/modules/cjs/loader:1404
throw err;
^Error: Cannot find module ‘ajv’
Require stack:After “require stack” there are other lines, if you need it, tell me.
Thanks -
i said stop
we need to fix nodejs so npm install will work
node -v
says something
and npm install says node is differenti am trying to figure out where node is installed and by who
system, nvm or nyou didn’t give me answers to the commands i provided
-
which node gave me
/home/MYMIRR/.nvm/versions/node/v22.15.0/bin/noden gave me
node/20.18.1Use up/down arrow keys to select a version, return key to install, d to delete, q to quit
nvm gave me
Node Version Manager (v0.39.5)
Note: refers to any version-like string nvm understands. This includes :
- full or partial version numbers, starting with an optional “v” (0.10, v0.1.2 , v1)
- default (built-in) aliases: node, stable, unstable, iojs, system
- custom aliases you define with
nvm alias foo
followed by a lot of options
-
@nowayto ok nvm and n do the same function but differently
i use n in my scripts because it runs everywhere
so lets turn off nvm
nvm deactivate nvm unload cd ~ rm -rf .nvmnow which node
should find /usr/local/bin/nodenow we need n to get to node 22.14.0
sudo n 22.14.0now node -v
should return 22.14.0
if so, do
cd ~/MagicMirror npm installnow MagicMirror should run
-
@sdetweil Thank you a lot Sam.

@nowayto so that sounds like the npm install failed again
do it again and show the output
