After updatering to Ionic CLI 4: Error: Cannot find module './binding'

Hi,

So I finally found the courage to answer YES to the update prompt that hits me every time I run “ionic serve”. And like always I regret it already, because… like always… when you update stuff in cordova/ionic shit gets broken.

So I updated from Ionic CLI 3.19.1 to 4.0.6. Before update everything worked perfectly, now when I run “ionic serve” I get:

 > ionic-v1 serve --host=0.0.0.0 --port=8100 --livereload-port=35729 --dev-port=53703 --engine=browser
[v1] (node:44339) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

Seems like it is something with the gulp file, so I’ve tried to delete all the contents in it, but no luck.
