Please try :

# uninstall previous Gulp installation if any.
npm uninstall gulp -g
cd [your_project_root]
npm uninstall gulp

# install Gulp 4 CLI tools globally from 4.0 GitHub branch
npm install gulpjs/gulp-cli#4.0 -g

# install Gulp 4 into your project
npm install gulpjs/gulp.git#4.0 --save-dev

Hopefully this solved the install problem
