Thx, after fixing this the next lib is missing. I just give up using that module.

I have a vision for the future MM development. All modules should run in a separate container/sandbox or capasulated/isolated somehow. So when they fail for whatever reason, the MM stays alive and reporting a specific error message.

Don’t get me wrong I highly appreciate the work/effort of michmich and his team.

cd ~/MagicMirror/modules/MMM-MyCalendar
npm init 

hit enter thru the prompts

npm install valid-url --save

the author should fix the module, but many authors are no longer maintaining their modules

what is the problem with MyCalendar?

I screwed up my MM entirely. pm2 crashed randomly for an unkown reason.

When did “npm intall” on all modules after the update to 2.16, mostly npm complaints about some vulnerabilites. So I did “npm audit fix” on all them all. Maybe some dependencies broke rather than being fixed.

Another thing; npm complaint that 2.16 is uncompatible with node 10.x and npm version. So upgraded both to the latest one.

Mostly like all that ruined my MM.

Thus, I loaded back last working backup and just did “npm install” on all modules. Npm is still complaints about the node version, but all module run except MMM-MyCalender which seems to be uncompatible with 2.16.

npm start or pm2

if pm2, the pm2 logs --lines=100

for any messages

loading is the default output til data arrives.
so it didn’t get the content from the api

is that forecast u are waiting for?
there is a timing issue, workaround with setting
(look it up for exact spelling)
initialLoadDelay:100

made it with npm install -g npm@6.14.14.

I still have issues with the default wheater module. The old “currentweather” module works but new default “weather” module just says “loading”.

you will then have to cleanup from 7

cd ~/MagicMirror
rm -rf node_modules
npm install

u may have to do the same in any module folder with a package.json file

How do I revert to npm v6?

I would fall back to npm 6

I got electron installed again with specifying a version (sudo npm install electron@6.1.12). No idea, why electron disappeared in the first place.

@Fozi

The MMM-MyCalender has indeed an issue with 2.16. causing a black screen. And MMM-Fuel is saying “undefined” for an unknown reason. Both modules are disabled for now.

My MM boots and shows the all other modules again.

With each MM update something crashes, mostly one of the 3rd party modules because one or more dependencies are lost/changed or deleted.

Thanks for your help. Great community!

I tried it again. Now the electron does not even start.

> magicmirror@2.16.0 start
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

sh: 1: ./node_modules/.bin/electron: not found

I tried to re-install electron with "sudo npm install electron@latest
", but no change.

So it looks to me as MMM-DWD-Pollen will be the problem.
That is faster, than going with disabled: true; and disabled: false; over all my modules :crossed_fingers: even it was a guess with the related module to me.

@Fozi now i have to see how to deal with your statement “When you found the module, that causes issues, contact the developer on github, or look for an alternative fork which seems to be maintained.”

Comment out this module in config and it works again.

Many thanks for your fast help!!!

disabled: true;

for each module and enable it one after the other by setting it to

disabled: false;

Taht might discover quicker, which module is the culprit instead of poking in logs (that is my personal approach!).

When you found the module, that causes issues, contact the developer on github, or look for an alternative fork which seems to be maintained.

Regarding the above mentioned MMM-MyCalendar module, I reverted to the default calendar module, which works just fine and delivers the same features.

read the startup messages

npm start
or
if using pm2
pm2 logs --lines=100

sudo git fetch --all
sudo git reset --hard origin/master
sudo git pull origin master

Uploading upgrade.log with 600 lines is not possible… because of file format.

After reboot I have only the mouse in the middle of the screen but MM is not working.

Also I’m not able to get a connection wit ma Web-Browser.

Raspberry itself is accessible via SSH.

Any idea?
