Error with node fetch for calendar on fresh install

[landaisbenj]

Hello.

After update, most of module cause some trouble from start. So, black screen…

I do a fresh install, without module, and i always have error on start :

[22.01.2022 22:41.16.390] [ERROR] WARNING! Could not load config file. Starting with default configuration. Error found: Error [ERR_REQUIRE_ESM]: require() of ES Module /home/pi/MagicMirror/node_modules/node-fetch/src/index.js from /home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js not supported.
Instead change the require of index.js in /home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js to a dynamic import() which is available in all CommonJS modules.

I can search on google, but i don’t find anything to resolve that… Do you have an idea ?

@landaisbenj never seen this using my install script

[landaisbenj]

Ok si i could try with your script today. I follow instruction on documentation.

@landaisbenj move the existing mm folder out of the way if doing install

cd ~
mv MagicMirror MagicMirror.save

OMG It’s really helpfull… Need to be the first way on documentation… Ok, it work, i try now to réinstall all my modules.

[landaisbenj]

All my module work. Thanks a lot… I’m on this by a few day…

@landaisbenj I have seen this error before. It comes from installing the latest version of node-fetch whereas the module uses an older version of node-fetch. The latest version is an ES module and must be import’d instead of require’d in the node_helper.

@mumblebaj but how did that happen? MM asks for newer, but module wants older?

[mumblebaj]

@sdetweil I would assume that the user may have installed a newer version. MM requires 2.6.6 which is not the ES version I think they changed from v3 onwards.
