how to update my MM

sdetweil

@rikko14 black screen… yeh. I added code to fix that but the bad file format problems prevented

do

pm2 stop all
pm2 flush
pm2 start 0

wait til MM comes up

pm2 stop all

then do this (1st post is enough)
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later

for each module reporting a missing library (there are more than 1 library potentially missing, so I don’t give you the exact command to issue, but teach you how to find the error and fix it from there)

then after fixing for all modules with problem,
(note you MAY have to repeat this looking thru the log part, I don’t know if they ALL will report, or if it will stop after the 1st error)

pm2 start 0

I’m not sure I understood and did the right thing …:

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

sdetweil

@rikko14 npm init -y

what is going on…

the instructions say

cd modulename (where modulename is the module having the error)

if the module does NOT provide a file called package.json, then do

npm init -y

why are you doing this in the users home folder?

RIKKO14

so i have to do first : cd ~/MagicMirror/ and after npm init -y that’s right ?

@mumblebaj said in how to update my MM:

what? check if what exist?

the problem here is that i looped thru all the installed modules, and found a package.json, which now requires a new
npm install

in the module folder, BUT, the npm install failed cause of the networking problem

one that is finished, I loop thru all the modules and check to see if they use one of the troublesome libraries
and do NOT reference it in package.json…
and if NO package.json, then I create one, and THEN do the npm install of the library

phew, all the same as the instructions i gave in the linked topic.

but there might be ANOTHER library too … that I don’t handle…

sdetweil

@rikko14 it says

to fix this you need to install the library in the module folder

cd ~/MagicMirror/modules

cd modulename (where modulename is the module having the error)

SO, you have to cd ~/MagicMirror/modules/modulename

same as every other time you were told to cd modulename

RIKKO14

I’m lost …
here are all the modules I have installed.

I have to do: cd ~ / MagicMirror / modules / modulename for each module and then npm init -y ?
and post here all the results of npm init -y ?

I have already had this Electron problem several times and I do not remember what I had typed as the command line but it was not that

@sdetweil said in how to update my MM:

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

@rikko14 look in the pm2 logs output

search for Cannot find module

sorry for the dual use of the word module. NPM calls the library a module and MagicMirror calls its app a module…

after that string, there will be a name in quotes ‘request’ or ‘valid-url’, or maybe something else

on one of the next lines will be a file path

MagicMirror/modules/??? some MagicMirror module name

THAT is the MagicMirror module which is missing the library found in the 'Cannot find module ’ message above

So, navigate to that MagicMirror module folder

cd ~/MagicMirror/modules/modulename

and then look for the package.json file

ls package.json

if you get ‘No such file or directory’ in response to the ls command, then create the file by doing

npm init -y

next step,

npm install ???
where ??? is the name of the missing library in the message ’ Cannot find module ’

done for this library for this MM module
