Hello,

I am converting a static site with a custom gulpfile.js to your gulp-site-generator setup. I used the subrepo approach. After adding all the dependencies to my package.json, I got this as result on first build:

> gulp

Anything wrong on my side?

Hi, not sure on the issue. It could be a version incompatibility. Will try and re-create and report back.

@ducksoupdev the node tools/install script did not add the required dependencies to my package.json. So I added the manually without specifying any version. So i got the latest. Once I reverted to the same versions as in the package.json of this repo, all worked correctly.
