What are the warnings?

Question

npm

The developers of PhpStorm in the latest releases abandoned automatic minification using YUI Compressor and suggested using other packages, I put:

C:\Users\Lenovo>npm i -g csso-cli uglify-js
C:\Users\Lenovo\AppData\Roaming\npm\csso -> C:\Users\Lenovo\AppData\Roaming\npm\node_modules\csso-cli\bin\csso
C:\Users\Lenovo\AppData\Roaming\npm\uglifyjs -> C:\Users\Lenovo\AppData\Roaming\npm\node_modules\uglify-js\bin\uglifyjs
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@~2.1.2 (node_modules\csso-cli\node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@2.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

+ uglify-js@3.10.1
+ csso-cli@3.0.0

What are two warnings?
Do you need to fix something?

Answer 1

No. You don't have to do anything. This is an optional dependency on fsevents (file watcher for linux), so you don't need it.
