@sdetweil

Thanks for info and pointers! Did the NPM install in base, but ended into a new obstacle.

@blackbull yes, I saw someone else with the same problem

it was the node-fetch version

do this

npm install node-fetch@2

[blackbull]

@sdetweil YES! Big thanks! :)

That needed to be run in the specific module folder, installing that in MM base did not work.

Respectfully,
Saku

@blackbull j’ai le meme soucis. quand tu dis le dossier spécifique du module, c’est par exemple dans MMM-moonraker ou dans MMM-moonraker/node_modules?

Merci d’avance.

[sdetweil]

@myayo001 did you see this above

[myayo001]

@sdetweil oui j’ai vu le post je dois installer npm install node-fetch@2
je l’ai installer dans le dossier MMM-moonraker et j’ai toujours l’erreur

[bugsounet]

@sdetweil cela arrive quand la version principale de node est v10.x et que l’utilisateur demande la version v20 ou v22 avec la commande n

généralement resolu avec la version principale de node en v20. ensuite on peux utiliser n comme on a envie

[myayo001]

@bugsounet je n 'ai pas trop compris ce que je devais faire.
mais j’ai bien node v20

Mirror $ node -v

v20.18.1

@myayo001 Just remove the the line const fetch = require("fetch"); in the file node-helper.js in the module’s directory.

merci ca fonctionne maintenant!
