@fufu1408 I had the thame Problem, but i solved it.

The Problem is nodered and the dependencies which are neede by the module.

1. fs-extra
2. node-fetch

They need node > 12 !

How to solve:

1. Update your System: sudo apt-get update && sudo apt-get upgrade
2. Install NodeRed: bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node14
3. be patient. This will take about 20-30 minutes !! The Script will do ALL the work for you!!
4. install fs-extra + node-fetsch: npm install fs-extra node_fetch
5. Update your MM: git pull
6. Install MM with: npm install (from inside your MM Directory)
7. Update MMM-Fuel: git pull
8. Install MMM-Fuel: npm install (from inside your MMM-Fuel Directory)
   Restart your System !!

Thats it !!
