Gulp as a task manager. Here's my config.
** Make sure you have Node installed. http://nodejs.org/
** Install gulp: npm install gulp -g
*** If you want to update the plugins you can use this on the root of your project folder (use sudo if you dont have the right)
npm install gulp-sass gulp-autoprefixer gulp-jshint gulp-concat gulp-uglify gulp-imagemin gulp-notify gulp-watch --save-dev
If there are two gulp versions. The CLI, and the project specific installed version.
To check the CLI and local version run: gulp -v To check the Installed project version via npm run: npm ls and look for gulp
Update the project specific version to 3.3.4 to solve that issue. From a terminal in your project folder: npm install gulp@3.3.4 --save
