[xMokAx]

i tired to install it normally using:
npm install -g browser-sync
then opened command prompt as administrator then tried again:
npm install -g browser-sync
then tried the solution mentioned here https://browsersync.io/docs/#windows-users i used this:
npm install -g browser-sync --msvs_version=2017
and i still got these errors:

i found the solution for this it's a problem with npm not browser sync and here is a link for it npm/npm#18380 and the temporary solution is to downgrade npm to 5.3 using this command npm install npm@5.3 -g.
