Error on starting MM2: module not present

[MWel1977]

@sdetweil
Oh…crap! :flushed_face: I have a node_modules folder under Home/Pi
not under Home/Pi/MagicMirror.
Think I’ll format my micro SD card and start over. This time when I install something for the MM I’ll do it from the directory Home/Pi/MagicMirror.
Don’t think I can just “move” the content of the Home/Pi/node_modules to the MagicMirror folder can I? :weary_face:

[sdetweil]

@mwel1977 just erase the one in /home/pi (rm -rf node_modules) and then start from the MM folder,

then erase node_modules, then do npm install, then switch to MMM-Swipe and do npm install,
then npm rebuild MMM-usonic

no need to wipe and start over…

[MWel1977]

@sdetweil If I understand you right:
#1 remove node_modules in “Home/Pi” and in “Home/Pi/MagicMirror” with command “rm -rf node_modules”
#2 re-install npm in the folder “Home/Pi/MagicMirror” and in “Home/Pi/MagicMirror/MMM-Swipe”
#3 then re-install the module mmm-usonic in the folder “Home/Pi/MagicMirror/MMM-Swipe”
#4 then rebuild the usonic module with “npm rebuild mmm-usonic”

I have doubt on where to install step 3. Should it go in the folder from the MagicMirror or from de module MMM-Swipe? Because I delete the module mmm-usonic with step 1. And I don’t know if this will be installed on re-installing the module MMM-Swipe.

But I’ll check that first thing tonight (if there is a module mmm-usonic being installed with MMM-Swipe). I think it should be installed with it as a dependency from MMM-Swipe.

[sdetweil]

@mwel1977 step 3, in the modules/MMM-Swipe folder,

npm install MMM-usonic

Then same folder,

npm rebuild MMM-usonic

@sdetweil
Did it tonight. couldn’t make it yesterday.
So…did as we sad like above…yet it didn’t work.
This time something with electron. Here’s the terminal “output”:

Can’t I just remove the MMM-Swipe module and reinstall it?

[MWel1977]

@sdetweil
Or can I better start clean and remove npm completely sudo npm uninstall npm -g and then reinstall?
I mean repearing all this could take longer than just simply uninstall and reinstall npm, MM2 and the few modules I have on this sd card. I just need the config.js file the store on a usb drive for when I’m done.

Or you think repearing that electron issue is a quick fix?:smiling_face_with_open_mouth_cold_sweat: :smiling_face_with_open_mouth_cold_sweat:

@mwel1977 said in Error on starting MM2: module not present:

sure… but u said that didn’t work before…

the package.json in MMM-Swipe is looking for electron version 1.2.1, very old…

I would edit the file before running npm install in the MMM-Swipe folder and chaneg the version to match
whatever electron verison is installed already…

MM/node_modules/electron/package.json

“version”: “2.0.13”

the MMM-Swipe package.json to

change

devDependencies": {
    "electron-rebuild": "^1.2.1"
  }

to

devDependencies": {
    "electron-rebuild": "^x.y.z"  === the electron version number above
  }

@sdetweil
I think I’ll just start over again with a reimage of the sd card.:persevering_face:
I’ve checked the package.json file in the electron folder and it showed version 2.0.16
So I entered that number at the bottom of the package.json file in the MMM-Swipe folder and run npm install again in the Swipe folder. Yet it gave me:

pi@Mirror:~/MagicMirror/modules/MMM-Swipe $ npm install
npm ERR! code ETARGET
npm ERR! notarget No matching version found for electron-rebuild@^2.0.16

Thanks for helping me out so far.
How do you know al this stuff? How long are you already doing this?
Hope I’ll get that smart one day. :grinning_face:
