Gulp Error: Cannot find module 'jshint/src/cli'
Solution 1:
You need to install jshint as well, that will sort out the issue.
> npm install --save-dev jshint gulp-jshint
Solution 2:
It turns out I need to use npm install --save-dev jshint gulp-jshint instead of npm install gulp-jshint --save-dev as the tutorial stated. Discussion around this was found at https://github.com/spalger/gulp-jshint/issues/131 with massive thanks to @user3042437 for suppling the link.
