how to update my MM

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

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? 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.

@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

@mumblebaj oh… no… don’t want to get into that

they are two distinct functions… users have to learn sometime

mumblebaj

@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

@mumblebaj they can’t mess up their install …

install aborted as already present

upgrade won’t change anything unless you ask for it.
and it won’t try to upgrade to the same version, unless you report it and I tell you how to get around it.
(I am constantly finding things that users don’t understand, and trying to make life easier as best I can)

this particular problem is unrelated to the scripts…

it was caused by a networking problem I can’t fix.
and I don’t know if all this will work .

I do this for the first modul :

pi@raspberrypi:~ $ cd ~/MagicMirror/modules/MMM-DHT-Sensor
pi@raspberrypi:~/MagicMirror/modules/MMM-DHT-Sensor $ ls package.json
package.json
pi@raspberrypi:~/MagicMirror/modules/MMM-DHT-Sensor $

i do this : npm init -y ?

sdetweil

@rikko14 no. the file exists.

only do npm init -y if the file does NOT exist

@sdetweil as you told me, I do cd ~/MagicMirror/modules/modulename for each module.
I found an error in the last module : MMM-WeatherOrNot, a module that I no longer use so I deleted it with the command : cd ~ / MagicMirror and rm -rf modules / MMM-WeatherOrNot then i redid pm2 save and pm2 start 0 and turned the MM off and on again with ~ 1 minute but I still have a black screen and an electron problem.
what to do ?
