Default Weather module still not displaying

[Jarhead96097]

@sdetweil Sam, thanks for all of your help. I’ve finished rebuilding without running ‘npm audit fix’ and everything is working as it should! I used your installation script and everything worked fine. I also took the opportunity to move things around and try a couple of new 3rd party modules… everything is back to normal!

Thanks again,
Jarhead96097

@Jarhead96097 said in Default Weather module still not displaying:

  const notificationPayload = {
  	currentWeather: this.weatherProvider?.currentWeatherObject?.simpleClone() ?? null,

thats line 158 and159.

the only thing i can think of is the ?. (optional chaining) operator…
but its been long supported… and it works on my 16.9.1 node version

see item 2 in the list here

@Jarhead96097 great news!!!

@sdetweil Moin, line 159 of weather-js looks like this:

currentWeather: this.weatherProvider?.currentWeatherObject?.simpleClone() ?? null,

The pm2 error log shows:

/home/<myusername>/.pm2/logs/MagicMirror-error.log last 50 lines:

Looks like I should re-install. Which is the best method, in your opinion?
Many thanks for your help - I want to get this thing on the wall soon!

@sdetweil Hi Sam, Many thanks for the suggestion - I followed your advice on that page. Here’s what happened halfway through:

  123 | template <class T, std::enable_if_t<!std::is_lvalue_reference_v<T>>* = nullptr>

and finally:

✖ MagicMirror Rebuild Failed

An unhandled error occurred inside electron-rebuild
node-gyp failed to rebuild '/home/<myusername>/MagicMirror/modules/MMM-PIR-Sensor/node_modules/epo                                     ll'.
Error: `make` failed with exit code: 2

This will all mean a lot more to you than it does for me.

@sdetweil And this is the final part of the error message, in bright red:

[sdetweil]

@Blackeye hm. 1st time I’ve seen his tools fail…

@bugsounet any guidance

[bugsounet]

@sdetweil yes

epoll/20.0.1 means it uses electron v20.0.1 for MagicMirror instead of v19.x that why it crash.

I’ll leave it up to you to explain it :)

[sdetweil]

@Blackeye ok, heres a way around the problem

fix MM install to have one new tool

cd ~/MagicMirror
npm install electron-rebuild

fix MMM-PIR-Sensor

cd ~/MagicMirror/modules/MMM-PIR-Sensor
nano package.json 

scroll down to

  "scripts": {
    "postinstall": "node_modules/.bin/electron-rebuild -e ../../node_modules/electron"
  },

change the postinstall line so it looks like this

  "scripts": {
    "postinstall": "~/MagicMirror/node_modules/.bin/electron-rebuild -e ../../node_modules/electron"
  },

ctrl-o to save the updated package.json
ctrl-x to exit the editor

then

npm install

should work correctly now

I just tested this on my MM 2.20 version, on both my linux machine and my pi4 with bullseye
