electron-rebuild and MagicMirror v2.18 (and more)

Awesome. It really works. I had the same issue and it was really frustrating, until i stumbled upon this solution. Great my PIR-sensor module was revived. I just followed the steps mentioned and voila…it has come back to life. Thanks a ton, it is selfless gentlemen like yourself who keep this world going. Kudos.

Hoping someone can help. Having the same issue with MMM-Reddit since updating to MM v2.20.0 . Spent a couple days scouring this as well as other forums for a fix. I already tried everything from this thread. Still getting the error below, no matter what I try. Any help would be greatly appreciated.

• MM v2.20.0
• Node v16.17.1
  -Node-gyp v9.2.0
  -NPM v8.15.0

This is the code I get for any rebuild or npm install…etc:

looks like u don’t have python version 2 installed

do python -v

[Dresch360]

@sdetweil Thanks Sam! Ughh…I feel pretty silly that I didn’t realize that. Was looking at the least obvious issue. Works perfectly after installing Python 2. Thanks again!

npm i magicmirror-rebuild

Thank you very much :-)

it works for me with another module “MMM-Buttons”, I’m so happy!
do you have to run npm i magicmirror-rebuild every time in each module folder?

[MMRIZE]

@Lusbueb
Usually, No.
Only the magic mirror module which use “native node module” needs it. but it would be hard to distinguish by a normal user.
