Blank mm after update

[sdetweil]

warning, warning… copy and save

MagicMirror/modules/node_modules/node_helper (folder, which contains index.js)

then

cd ~/MagicMirror/modules/mmm-weatherchart
npm install del

check for a missing
MagicMirror/modules/node_modules/node_helper folder
and if so, copy it back

i opened an issue with mmm-weatherchart

seems odd that there would be two invocations of these modules…

I have only one mmm-weatherchart module present.
When disabled everything is fine.
However, I forgot to remove the single quotes, as I just copy/pasted the config from the thread.
Corrected it, but now I get even stronger things.

0|mm  | WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'del'

I do not have any string with ‘del’ in my config :worried_face:

@evroom see my prior most about the missing module

I was typing while you answered.
Will have a look at it and try it out.

The module is running now, but I get this error:

0|mm  | Downloading weather map with signal: FETCH_MAP From URL: www.yr.no/place/Germany/Bavaria/Nuremberg/meteogram.png
0|mm  | Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1567097174409.png'

Then I read somewhere there is a clone of this module that is more recent, so I tried that:

https://github.com/szech/mmm-weatherchart

Same result: module runs but no file in the cache dir.
When opening the URL in the browser, it does show the picture that I do not see on my screen.

Oh boy/girl, thought it was a simple syntax thingy in config.js …

[sdetweil]

the module doesn’t work, but doesn’t kill MagicMirror anymore…

@sdetweil said in Blank mm after update:

Correct.

I have a few questions.

In the original module there is no package.json file, where in the cloned one there is.
So, when using the original module, you should NOT use npm install, right ?
First of all it will no do anything useful, but it WILL delete your /home/pi/MagicMirror/modules/node_modules/node_helperdirectory and its index.js file.
When using the cloned module, you should run npm installin order to install the dependencies mentioned in it, right ?
No harm is done to the node_helper dir.

Or is it all BS I am telling here (and made the wrong observations) ??

[sdetweil]

@evroom i cloned and got no package.json
i cloned this
https://github.com/paphko/mmm-weatherchart

[sdetweil]

@evroom yes, to all your observations…

[evroom]

When I use
$ git clone https://github.com/szech/mmm-weatherchart.git
then it works.
The README.md from szech point to papkto.
When corrected and doing npm install in the mmm-weatherchart directory, it works

[sdetweil]

@evroom yes, that module has it…

[kvicksson]

@sdetweil Thanks! This worked for me as it doesn’t kill it anymore. Hope for a quick fix. Can I follow the process somewhere?

[evroom]

Hi @kvicksson ,

To me it seems there are 3 problems here.
You could have a look what the pm2 log says:

$ pm2 logs --lines 100

You will either have:

Error: Cannot find module 'del'

or:

Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1567097174409.

or something completely different.

The 3 problems and potential solutions:

You’re config.js entries:

updateInterval: '3600000',
hideBorder: 'true'

should be:

updateInterval: 3600000,
hideBorder: true

even if the module could potentially handle it.

If your mmm-weatherchart instal has this file present:

/home/pi/MagicMirror/modules/mmm-weatherchart/package.json

then you should run:

$ cd /home/pi/MagicMirror/modules/mmm-weatherchart/
$ npm install

If your mmm-weatherchart instal has this file NOT present:

/home/pi/MagicMirror/modules/mmm-weatherchart/package.json

then you should NOT run npm instal, has it will cause havoc to you MagicMirror install.
I would do this in this situation:

$ cd /home/pi/MagicMirror/modules/
$ mv mmm-weatherchart mmm-weatherchart.saved
$ git clone https://github.com/szech/mmm-weatherchart.git
$ cd /home/pi/MagicMirror/modules/mmm-weatherchart
$ npm install

$ pm2 restart pm2
$ pm2 logs --lines 100

When it works:

$ cd /home/pi/MagicMirror/modules/
$ rm -rf mmm-weatherchart.saved

Good luck !!

PS @sdetweil : please comment if I am wrong or made mistakes somewhere & thanks for your input.

this is all volunteer… you could post an issue to the module owners github repo… maybe he or someone else will respond… I am like you, just another user…

@kvicksson said in Blank mm after update:

@sdetweil Thanks! This worked for me

I should type faster :-)

[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

[evroom]

@sdetweil said in Blank mm after update:

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…

[evroom]

@kvicksson said in Blank mm after update:

so don’t have to bother right now?

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.
