Hello. I am working in Mac (capitan) and when i run gulp it show an console error it only happens in a fresh gulp project

I reinstalled my project and created again many times.

gulp-sass requires through2 which hasn't seem to have installed properly. This isn't a gulp issue it's an NPM issue. Try clearing your node modules and trying again.

Also for future reference, github is used primarily as an issue tracker for the gulp team and not for user support, stack overflow is the best place for these things.

I am intalling module per module again. I think it was a gulp bug in capitan -_-

[rollrodrig]

I just copies the same package.js from other project to avoid install package per package again

Problem with your npm.
