After installing gulp#4 (the next version of gulp npm install 'gulpjs/gulp.git#4.0' --save-dev ) I was doing a couple of tests and ended up going to the last version but the console kept printing me the following output AssertionError [ERR_ASSERTION]: Task function must be specified I've tried several things like changing branch, removing the node_modules and installing a different gulp version like gulp@3 but none work
$ npm run watch
> cx-content-extractor@0.0.1 watch /Users/alevale/work/CLIENT
> gulp watch
assert.js:60
throw new errors.AssertionError({

Wanna share my silly mistake ^^
After a couple of tries it seemed like the changes I did were saved in the package-lock.json and I forgot to delete that file as well when getting the environment in a "clean state"
