Default Weather module still not displaying

[sdetweil]

@Jarhead96097 great news!!!

[Blackeye]

@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:
1|MagicMir | failed to load swrast driver

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:

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

@sdetweil said in Default Weather module still not displaying:

~/MagicMirror/node_modules/.bin/electron-rebuild -e …/…/node_modules/electron

Yes! It installed correctly this time, so that change in the path did the trick. I did get some warnings however:

npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain cir                                 cumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

So it is not quite a perfect solution, but it works!
Many thanks for the suggestions and the solution!

[sdetweil]

@Blackeye ignore the warnings, nothing we can do about them.

the ‘problem’ here is that the compiler needs to know what version of electron to build for, but can’t figure it out.

using electron-rebuild from the mm libs solves that
