How do I install gulp 4

Question

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.
