v22.15.0I don’t know what happened.
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

@nowayto weird, and npm start fails again _ not defined?
i installed solarpicture without problems
-
@sdetweil
I’m sure.I don’t think SolarPicture could be the problem.Yes, the error keep showing
-
@nowayto wild, lets do this… intall MM again, but save the current…
#backup MM config and modules list bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)" #rename the MagicMirror folder out of the way cd ~ mv MagicMirror MagicMirror.save #and install MM again bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)" #restore the MM config and modules bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_restore.sh)"then
cd ~/MagicMirror npm start -

Before writing here I made backups, locally and on github, like you taught me in the past :)Now I’ll try

@nowayto wow!!! NOW i am really confused.
have you rebooted?
if you try the sample config.js
cd ~/MagicMirror/config mv config.js config.js.save cp config.js.sample config.jsand then
npm startdoes it run or fail
-
@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 no coffee needed, we found it!!!
please NEVER use sudo inside MagicMirror folder
no reason to use super user , just makes trouble laterso if you fix the config.js in the saved MagicMirror folder then it should run ok too!!!"
ill see what we can do about the misleading message… thanks for your energy here!!!
