<![CDATA[Cannot find module 'node-fetch' error with multiple MM modules]]>Hi,

I have several failing with the “Cannot find module ‘node-fetch’” error. (see trace below)
I have seen this with similar other (older) modules, and sadly I have not been able to fix this.

https://github.com/alonsourbano/publika
https://github.com/ZakarFin/mm-hsl-timetable
https://github.com/cSharpBastard/mmm-nordic-electrical-spot-prices

Browsing the forums, there seems to be similar issues with other modules after the MM 2.25.0 version.

Things tried (which I can recall):

All with similar results. Any advice appreciated, thanks!

Respectfully,
Saku

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

Merci d’avance.

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

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

BR,

So you can either NPM install it in every module that needs it or you can an NPM install it in the base once for all the modules
