npm error A complete log of this run can be found in: /root/.npm/_logs/2025-05-10T06_41_52_949Z-debug-0.log

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

[email protected] 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
