[ERROR] _ is not defined

[nowayto]

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

Node.js v20.18.1

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 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

@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 out

https://forum.magicmirror.builders/topic/19561/version-2.31.0-april-1-2025-upgrade-reminder

[nowayto]

@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

[nowayto]

@sdetweil Do you suggest to update manually or auto? Thanks

[sdetweil]

@nowayto i never suggest update automatically.
use my script

[nowayto]

@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

[sdetweil]

@nowayto yes, but its two steps

one time without any parameters (test mode)
and one time with apply

all 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

[nowayto]

@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 persist
