MM cant boot, wont boot!

[nicoz]

Hi,
Complete noob here so please word your responses for 10 year olds :-)

Recently my MagicMirror has been booting to a black sceen. A literal black screen, and the only way to remove it is to minimize the window.
I think the problem started when i tried to update the program. I have tried since to update and think i have succeeded however now it seems not not boot at all. Even manually via SSH

My pi just boots to the standard UI.

Any Ideas???

@nicoz if u updated, (git pull) did u npm install after?

also, sometimes existing modules need to have their stuff refreshed after the base refreshes
(all leading to black screen)

I have a script for future updates that figures this all out…

in the short term, make sure you did

cd ~/MagicMirror
npm install

then check each module folder, and if there is an package.json file, also do the

npm install 

for each such folder
then restart mm

One other thing you can do is run “npm run config:check” in the magicmirror root directory (~/MagicMirror) - it’ll run through and see if there’s anything that’s slightly out of wack to blank the mirror but not out of wack enough to throw an error. It’s saved me lots of headaches several times.

npm install seemed to work in that i dont get a black screen anymore.

npm start will start the mirror but for some reason it wont stay open. i come back to the mirror and i am back at the Rasbian Home screen?

i also tried config:check but i dont really know what im looking at

[sdetweil]

@nicoz when u do npm start is shows messages to the screen…

can you do

npm start > somefile 2>&1

and when it ends, look at somefile

I am having this same issue. I ran the update and everything was fine except my calendar and the 2 day weather thing, which looks like a known bug. I rebooted and am only getting a black screen with the mouse cursor. I did some digging and ran the npm install on the main magic mirror directory, and the directories for the modules i’m using, and it’s still not working. I tried to do the npm run config:check and it came back with an error saying " > magicmirror@2.11.0 config:check /home/pi/MagicMirror

[sdetweil]

@Cyric u ran the update? how?

[sdetweil]

@sdetweil can u open the developers window, ctrl-shift-i, select the tab labeled console, and scroll up to see any errors

[Cyric]

@sdetweil I did git pull in the ~/MagicMirror parent directory. That gave me a few errors about changes, so i just did git pull --hard. Then I did npm install. For the other modules, i just did git pull and npm install.

[Cyric]

@sdetweil Im sorry, where do i do this at?

[sdetweil]

@Cyric on the mirror black screen

[Cyric]

@sdetweil when I go into the developer console, it says " devtools was disconnected from the page. Once the page is reloaded, devtools will automatically reconnect."

If I x out of that and go to console, it’s empty.

[Cyric]

More troubleshooting: I deleted the config.js and it loaded and said I needed to load a config.js file. I loaded the sample one, and it went back ot being a black screen.

[sdetweil]

@Cyric ok, where do u start mm? pm2 or nom start manually

if pm2 do

pm2 logs --lines=100

if nom start, the console output is right there.

let us know what u find

[Cyric]

@sdetweil Here is what it gave me when i tried npm start:
"magicmirror@2.11.0 start /home/pi/MagicMirror

@Cyric >Cannot find module ‘ical’

hm…
the calendar reader module is not found

can you do

cd ~/MagicMirror
rm package-lock.json
rm -rf node_ modules
npm install

[Cyric]

I ran that, then did npm start again. It told me: "> magicmirror@2.11.0 start /home/pi/MagicMirror

Now it won’t load the black screen. I have not rebooted yet.

[sdetweil]

@Cyric weird

cd ~/MagicMirror
git checkout modules/default/defaultmodules.js

@sdetweil ok, progress. It started magic mirror with a black screen and no mouse. Before it was a black screen with the mouse, and it said electron instead of magic mirror 2. I rebooted and tried to reload my config.js, but it didn’t help.
