Blank mm after update

sdetweil

@evroom think u have good instructions…

ps, 2 of my three systems do not have pi as the user, so the path is wrong, and in the module defaults too

Yes, I assumed user pi and the install under the user pi home directory.
Will try to remember that in the future.
Tilde for the home directory should work on all platforms, is my understanding.

~/MagicMirror

My keyboard is lacking a tilde and I always forget the right keystrokes.
So /home/pi is faster. :-)

@evroom I sat right now and installed a new calendar module and suddenly the mmm-weatherchart started working… :thinking_face:

Did the $ pm2 logs --lines 100 and got a lot of errors, but I guess because everything’s working fine so don’t have to bother right now?!

kvicksson

And of course it didn’t work now when I tried to switch back to default calendar module and then back to the other calendar module…

As long as the errors are no fatal errors that do not prevent the MagicMirror from starting or prevent a certain module from working right, you might chose to ignore them.
But the problem is, that when you add something new or update something existing, it becomes more and more difficult to debug and/or correct in case of problems.

When you do this:

$ pm2 flush
$ pm2 restart mm
$ pm2 logs --lines 100

what is the first error you see ?
Perhaps you post the first 50 to 100 lines of the log.

But only if you want to spend some time on it, when not that’s fine too.

@evroom actually no errors like I got before…

I really appreciate you want to look into my errors, I’m not too good on this :)

@kvicksson

Doesn’t look too bad.
Probably you saw the previous errors in your log output, that it is why flushing (pm2 flush) sometimes cannot hurt.

In order to know a bit about your environment, can you post the output of the following commands ?
I am assuming you are using a Raspberry Pi

$ cat /proc/device-tree/model
$ lsb_release -a
$ npm --version
$ node --version
$ pm2 --version
$ cat /boot/config.txt | egrep -v '^$|^#|^\['

I also would suggest to see if npm shows any errors:

$ cd ~/MagicMirror
$ npm audit

In my case a

$ npm audit fix

solved the dependency issues it found.

Perhaps others have different ideas, but as a hobbyist, I would take these steps first myself.

The npm audit warnings do not create any problems in running the mirror as far as I know. They also do not show up in the pm2 logs.
I would even be very careful as an inexperienced user to do that. “Fixing” these npm warnings on the root MM install could break the whole mirror (not the mirror itself of course :-)). Especially if you mess with the electron/chromium dependencies.

@evroom got an error on the egrep command:

Forgot to escape the [, try this:

cat /boot/config.txt | egrep -v '^$|^#|^\['

EDIT: Did not forget to escape it, it is this shitty forum that removes it.

There needs to a backslash \ before the last [
