browser-sync installed by npm is not working

Question

I'm trying to install browser-sync using npm line and I get:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@~2.1.2 (node_modules\browser-sync\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"})

I tried updating node (uninstalled and installed it again) current version is v12.18.2 and npm 6.14.6

only weird thing i did before was running this line npm install -g npm@latest which i did not notice was for mac.

when I call for the version (browser-sync --version) i get

YError: Invalid first argument. Expected boolean or string but received function.

thanks!

Ciao, these are warnings not errors. If you tipe in command prompt `browser-sync -v` what do you see? — Giovanni Esposito, Jul 20 '20 at 00:30
As stated above it is a warning about an optional dependency not supported by your platform. The NPM ecosystem sadly has lots of these warnings making people start ignoring these warnings and thus missing real problems. — ext, Jul 20 '20 at 00:34
I updated the post and added what I get when I prompt browser-sync --version I already see that this warnings are a big deal around npm but in my case it seems that it crashes the package as it does not work — Soyrbto, Jul 20 '20 at 00:45
[This](https://medium.com/@gichuwil/browsersync-on-windows-10-workaround-2173fb1f71a4) post is old but could help. — Giovanni Esposito, Jul 20 '20 at 00:51
@giovanniEsposito thanks for the quick reply and looking up the article, but it seems that the tree folder has changed as it was no browser-sync in my nodejs installation and there where 3 folders in node modules (browser-sync, browser--sync-client, browser-sync-ui) it looks like that fix is outdated — Soyrbto, Jul 20 '20 at 01:05

The problem seems to reside in the newest version of browser-sync, I rolled back to an older version and seems to be working fine

npm install -g browser-sync@2.26.7
