I am working on an Ionic 1 app with a remote team and lately our versions have not liked each other. I was wondering if the fact that I have also been working on Ionic 2 projects for whatever reason my CLI "thinks" these apps are also Ionic 2 and there for is shooting me the error below?
ionic build ios

WARN: ionic.project has been renamed to ionic.config.json, please rename it.
(node:9061) 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.
Uh oh! Looks like you're missing a module in your gulpfile:
Cannot find module 'bower'

Do you need to run `npm install`?

I have ran npm install.. does not make it go away.. I also have make sure to have bower installed.
What does this hold up here have to do with? I've been stuck here for a couple days now.

UPDATE

I went to an old project that and i tried to run ionic info to see the versions I have and system info but I get THE SAME error message..
I have no idea what I've done to get this...

mymac ~/code/92_AAC/newApp on master[!]
$ ionic info
WARN: ionic.project has been renamed to ionic.config.json, please rename it.
Uh oh! Looks like you're missing a module in your gulpfile:
Cannot find module 'gulp'

Do you need to run `npm install`?

UPDATE 2

I downgraded from Node 6 to Node 5.9 On the current project I was having the original issues.. I got this..

$ ionic build ios
******************************************************
 Dependency warning - for the CLI to run correctly,      
 it is highly recommended to install/upgrade the following:     

 Install ios-sim to deploy iOS applications. `npm install -g ios-sim` (may require sudo)
 Install ios-deploy to deploy iOS applications to devices. `npm install -g ios-deploy` (may require sudo)

1. List item: The main error (A4CPassenger@1.1.1 - not sure what to call this.. but this was basically the name of the app? I believe the remote team changed it.. for whatever reason I am still getting the old name..)
