MM2 will not start after update

[killing joke]

Hey @ all,

I updated my RP3 B+ with the following commands sudo apt-get update and sudo apt-get upgrade
and my MagicMirror 2 with the following command cd ~/MagicMirror && git pull
The last one got some errors so I had git reset --hard and thengit pull $$ npm install it (as decribed here: update MagicMirror error - link to this forum) but now I can´t start the Mirror with npm start at the folder: ~/MagicMirror.

This is the message which occurs:

> magicmirror@2.11.0 start /home/pi/MagicMirror
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

Any suggestions how to solve it?
Thanks in advance

@killing-joke for every module that has a package.json file, you need to do an
npm install
in their folder too

my upgrade script would have helped here, see

Hi @sdetweil,
this is my “second” pi and it´s an free-external-module pi.
Anyhow. I used your code but it didn´t worked for me/my pi - same error occurs.

Unfortunately there is no log file “install.log” in the MagicMirror folder.
Files in my MM folder:

• CHANGELOG.m d
• core (without file ending)
• dangerfile.js
• Gruntfile.js
• index.html
• jsconfig.json
• LICENSE.m d
• module-types.ts
• package.json
• package-lock.json
• README.m d

confused any suggestions?

@killing-joke said in MM2 will not start after update:

correct, if I am installing, I cannot out the loh IN the MM folder as it doesn’t exist yet,
so its in the user root ~/install.log

but there IS an upgrade.log in the installers folder as it said when it started
and its two pass, right?? 1st time to test, second time with more arguments to actually DO the upgrade

AND if you did it manually once, you will have to FORCE it
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)” force

install is NEW (if u ran install again there should be a log at ~/install.log)
upgrade is update MM versions

Hi @sdetweil,

I found the log file. I translated it into english

@killing-joke that is install, and something is already running.

Upgrade is different script.

Hi @sdetweil

@killing-joke said in MM2 will not start after update:

this is a two pass process… I tell you what MIGHT need to be done
then you run it again with ‘apply’ at the end of the command and i DO the update
this is for people that have lots of things that break on each update…

was a typo. It should be "Afterwards I performed npm update and npm restart and it helped.

Thank you very much.
