Ionic move to a new development computer

Hi guys,

I have a project that is built on v1.
Recently bought a mac so transferred by project to the mac.
Installed node, npm, cordova and ionic.

I simply copied the project root folder and placed on the new computer.
then used terminal to go to the project root folder and ran npm install.

I get the below error when I’m trying “ionic serve”.

{ Error: Cannot find module '/Applications/MAMP/htdocs/TheAppLocation/node_modules/ionic’
at Function.Module._resolveFilename (module.js:527:15)
at Function.Module._load (module.js:476:23)
at Module.require (module.js:568:17)
at require (internal/module.js:11:18)
at /usr/local/lib/node_modules/ionic/bin/ionic:18:13
at code: ‘MODULE_NOT_FOUND’ }

I get the above same error even if I try ionic info in the project folder.

I just get the feeling that ionic as to not being installed or something.
Any help is greatly appreciated since I am getting desperate.

That’s a bad idea. Please use version control such as git instead.
