This is a small tip i want to share with you.
Sometimes when you are playing around with Node dependencies you can come into an issue like this
Error: EPERM: operation not permitted, chmod ' when running `gulp``
That error can occur if you have been running
sudo npm install`` on a Virtual machine like Vagrant, and now you are trying to rungulp`` it fails with the error message just described.
It turns out that you don’t have to run
`sudo npm install``` again as Administrator, and doing so won’t fix the problem. Trynpm cache clean
and delete your compiledCSS/JS` first.
Hope it helps, this has always fixed things for me.
