Cannot find module 'node-fetch' error with multiple MM modules

blackbull

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):

npm install of that missing ‘node-fetch’
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later?page=1
Fresh MM installations with Node.js version 20
https://github.com/nodesource/distributions
downgrading to Node.js version 18

All with similar results. Any advice appreciated, thanks!

Respectfully,
Saku

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

it was the node-fetch version

do this

npm install node-fetch@2

sdetweil

@blackbull we remove node fetch from the magic mirror package on this release as we drop back to the integrated fetch that’s provided in node and in the electron browser unfortunately that breaks a bunch of modules.

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

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

@sdetweil YES! Big thanks! :)

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