MM won't run, blank screen with cursor showing after updating

[jmartin1009]

When i went to go update, it said i had three files that were preventing it from updating, so i deleted them as i said, was package.json, package-lock.json, and vendor/package.json (I think). After updating, i try to run it and it gives a blank screen with the cursor showing and this is what shows in the terminal.

pi@raspberrypi:~/MagicMirror $ npm start

> magicmirror@2.8.0 start /home/pi/MagicMirror
> sh run-start.sh

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.

It launched and worked fine beforehand, i was just updating because i was getting an error for some reason with MMM-Voice and thought maybe if i updated it would work.

@jmartin1009 after downloading the code (with git pull) , you need to do

cd ~/MagicMirror
npm install

also, if u have modules other than the default, you must ALSO do
nom install in each module folder where there is a package.json file present to cleanup the new dependencies

in the future, i hope my updater script (link to topic below) will be available as part of the package to help solve these kinds of problems…

@sdetweil Thank you for the quick answer! Doing that as we speak.Do you however also have any knowledge about MMM-Voice? Running into an error there as well, that’s what prompted the update. Thanks!

[jmartin1009]

@sdetweil i did npm install in the cd magicmirror folder, as well as the other folders with a package.json, but it is still doing and saying the same thing as before, any ideas?

[sdetweil]

@jmartin1009

cd MagicMirror/node_modules
ls rrule

does anything show?

if not (expect it to be not there)

cd ..
npm install rrule

also, edit package.json

u should see this

"rrule": "^2.6.2",

[jmartin1009]

@sdetweil i installed rrule in just the normal folder, or the blank cd. where should i edit the package file? like in which folders?

[sdetweil]

@jmartin1009 everything MagicMirror starts in the MagicMirror folder…

in just the normal folder,

what does that mean?
it MUST be in MagicMirror to update the runtime files…

the

cd .. (you were in node_modules, so back up one level, now in MagicMirror)
npm install rrule

was exact, if you followed my instructions

[jmartin1009]

@sdetweil i accidentally installed it in the folder previous to MM, but it still worked, but im installing it in the MM folder right now. Thought you meant the first level cd. Should i remove it in the pi folder? If so how because it doesn’t show up

[sdetweil]

@jmartin1009 sure

cd ~
npm uninstall rrule

[jmartin1009]

@sdetweil how do i fix this?
