Success! I ran the following command:

npm install node-fetch@2

… and now it’s back up and running again! Thanks for the quick response!

npm install node-fetch will install the latest version which is a v3.x

mm does not support typescript and so needs a v2.x version.

you have to look up the latest v2.x release and install this. This is a problem of MMM-Weather and should be fixed there.

Ok. I went to my /home/pi/MagicMirror/modules/MMM-Weather/ folder and I ran the ‘npm install node-fetch’ command. I am getting a different error now:

The procedure continues to indicate that I need to change directories to the module that is having the problem, but it doesn’t exist…

I don’t understand

/home/pi/MagicMirror/modules/MMM-Weather/

is the module having trouble…

that is the folder to be active for the rest of my instructions

Cannot find module ‘node-fetch’

this library was removed from the base in 2.25
