I've been using gulp-watch. The current version of gulp-watch relies on the call gulp.parrallel. This call is only available from gulp 4.
However gulp 4 is not available via the npm repo.
npm info gulp dist-tags
returns: { latest: '3.9.0' }
.
I can see that there is a 4.0 branch within the git repo. But attempting to install it with variations on this command fails: npm install https://github.com/gulpjs/gulp#v4.0.0
.
npm install gulpjs/gulp.git#4.0 --save-dev
