npm seems to see an old version of nodejs but:

~/MagicMirror $ node -v
v22.15.0

I 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 2.31.0

doing 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

force

to the end

[sdetweil]

@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
nvm 

dont do anything else til we figure out the nodejs problem

[nowayto]

@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.js

node: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

[sdetweil]

@nowayto

i said stop

we need to fix nodejs so npm install will work

node -v

says something
and npm install says node is different

i am trying to figure out where node is installed and by who
system, nvm or n

you didn’t give me answers to the commands i provided

[nowayto]

@sdetweil

which node gave me
/home/MYMIRR/.nvm/versions/node/v22.15.0/bin/node

n gave me
node/20.18.1

Use 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

[sdetweil]

@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  .nvm

now which node
should find /usr/local/bin/node

now we need n to get to node 22.14.0

sudo n 22.14.0

now node -v

should return 22.14.0

if so, do

cd  ~/MagicMirror 
npm install

now MagicMirror should run

[nowayto]

@sdetweil Thank you a lot Sam.

I did everything but
I have an [ERROR] _ is not defined

@nowayto so that sounds like the npm install failed again

do it again and show the output

[nowayto]

@sdetweil

installer didn’t failed, but this is the result now

npm install

[sdetweil]

@nowayto weird, and npm start fails again _ not defined?

i installed solarpicture without problems

[nowayto]

@sdetweil
I’m sure.I don’t think SolarPicture could be the problem.

Yes, the error keep showing

[sdetweil]

@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 

[nowayto]

@sdetweil
Before writing here I made backups, locally and on github, like you taught me in the past :)

Now I’ll try

[nowayto]

@sdetweil

That’s incredible… I did it, everything goes good… no issues but when I start it

npm start

magicmirror@2.31.0 start
npm run start:x11

magicmirror@2.31.0 start:x11
DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

Again this _ is not defined

[sdetweil]

@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.js

and then
npm start

does it run or fail

[nowayto]

@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 config

npm 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

[sdetweil]

@nowayto no coffee needed, we found it!!!

please NEVER use sudo inside MagicMirror folder
no reason to use super user , just makes trouble later

so 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!!!

[sdetweil]

@nowayto i use ctrl-end on my keyboard for nano to get to end of file

haven’t found a way to do that on my chromebook, drives me crazy!!!

[sdetweil]

@nowayto ok, I’ve found the error producer
and I’ll propose a fix…

I think this might have been more useful lol
