@sdetweil :-) I understand. But it would make your life easier with running the wrong script, messing up their install and you having to go through a 100 different things for them to do to get it fixed… :-)

@sdetweil said in how to update my MM:

what? check if what exist?

What I was referring to is for a single script to run, check if MagicMirror exist, check version and upgrade if not on the latest, if not exist then do a fresh install. This way whoever runs your script does not run the wrong one. Just a suggestion.

@sdetweil Maybe combine the script and check if exist then update, else frsh install? Would that work?

@sdetweil And so it begins. Modules like the MMM-Hue and others that talk to internal devices on the local network is going to become a problem.

@vince Have a read through this below thread. There is a possible solution there as well.

@sdetweil :thumbs_up:

@richard238 run npm i mysql --force The stylint is a dev dependency.

@richard238 In the MMM-MysqlQuery folder, npm i mysql

@richard238 seems like styleint is giving issues, Can you just try and install mysql and see if that resolves your issue?

@richard238 can you check if package-lock.json exist. if it does delete it rm package-lock.json then try again. Also, did you do the uninstall in the MagicMirror folder first?

@richard238 Just google update npm and update node. Once those are updated then you can do the rest. Uninstall mysql and run npm install in the MMM-MysqlQuery folder. Hopefully that will resolve the issues.

@richard238 You want to update both first.

@richard238 It seems your versions of npm and node might be older than the required versions. run the following

node -v
npm -v

@richard238 I think you installed the latest version in the MagicMirror folder whereas the MysqlQuery wants version 6.4.1. Go to the root of MagicMirror and run npm uninstall mysql. Once that is done then cd modules/MMM-MysqlQuery. Then just run npm install in the folder. It should then install the dependencies that it require.

@richard238 No, You need to do the following:

cd ~.MagicMirror/modules/MMM-MysqlQuery
npm init -y
npm install mysql --save

There may be other missing modules.

@richard238 said in v2.18.0 update gave black screen, then nothing.:

0|MagicMir | [06.01.2022 08:34.09.653] [ERROR] App threw an error during load
0|MagicMir | [06.01.2022 08:34.09.658] [ERROR] Error: Cannot find module ‘mysql’

Your error!

@richard238 Have a look at the below post. It might solve some of your issues.

@karsten13 So I have been tinkering with the MMM-Hue module a bit and have replaced jQuery which seems to invoke XMLHttpRequest, with node-fetch, albeit the older version (2.6.1) of node-fetch, but it now returns data without requiring a certificate and the use of https.

@sdetweil Thanks Sam. That sorted it.

@sdetweil Have you seen these errors before? Mirror still starts though. I have just noticed it now as I usually start my mirror from the cron.
