(solved) MM 2.18 - skipping optional Dependencys

OberfragGER

Hi,

after a regular Update MM2.17 -> 2.18 ich recieved the Warning:

MagicMirror installation finished successfully!


> magicmirror@2.18.0 prepare /home/pi/MagicMirror
> [ -f node_modules/.bin/husky ] && husky install || echo no husky installed.

husky - Git hooks installed
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^2.3.2 (node_modules/jest-haste-map/node_modules/fsevents):

Somehow- what do i have to perform to install this dependency…?

npm install typescript
npm install tsutils

Both have been sucessful.

This is hindering me to update NPM to Version 8.x.

pi@MagicMirror:~/MagicMirror $ npm install fsevents

Ich have found the answer by meyself.

npm install --no-optional
npm install typescript
npm install tsutils

@oberfragger I don’t understand.

these optional libs are platform dependent.

as such the fsevents uses macos only functions and CANNOT run on Linux/pi…

that is why they are OPTIONAL

no error if not installed.

@sdetweil Youre right,
but my inner monk says… warnings are no good. Please fix it ;)

sdetweil

@oberfragger we cannot fix it… not our code and no overide of messages is available

same as Audit

OberfragGER

@sdetweil No. This fix it was not meant by you- it was for me… “but my inner monk says (to myself)… warnings are no good. Please fix it 😉”
