Mind letting us know? https://github.com/driftyco/ionic-cli/issues

UPDATE:
I even tried:
brew uninstall node
brew install node

UPDATE:
I have also tried yarn CLI
could not get it to work.

I have also tried to make sure all my permissions on npm on my dev is OK with new build and installs and re-installs and re-builds of my dev machine multiple times. Ref:
https://docs.npmjs.com/getting-started/fixing-npm-permissions

then...
npm install -g ionic cordova
...nope still not working.
OK, I gotta just stop and drop out of Ionic 2 for a while.Too many changes to the framework and breaking my builds almost twice weekly. Killing me. Anyway, it's back to latest build of Android Studio for the next few days I guess until we get some solid resolutions to these build issues.

** #UPDATE 11/21/2016: Houston, we have a go woohoo!**
Ughhhh....kool finally can go back to work with Ionic 2!
OK: Found the fix here: https://forum.ionicframework.com/t/ionic-command-not-work/19452/5You'll want to edit the file, .eg:
sudo nano /usr/local/lib/node_modules/ionic-app-lib/lib/config.js

or $ cd /usr/local/lib/node_modules/ionic-app-lib/lib/
$ atom . or $code . or whatever. Open the config.js file in the dir

then....change line 7 as it is if you install ionic@latest as of 11/21/2016:
CONFIG_FILE: '.ionic/ionic.config',
To have a slash after the dot:

CONFIG_FILE: './ionic/ionic.config',

Then save the file, and try running an ionic command:
ionic info or whatever Ionic CLI command you need to run!
Done.

CONFIG_FILE: '.ionic/ionic.config',
To have a slash after the dot:

CONFIG_FILE: './ionic/ionic.config',

is the right answer thanks ;)

[finalxcode]

thanks

Just delete {user}/.ionic/ionic.config.json and run ionic serve
It will be fixed.
Delete this from terminal.

@seokochin solution worked like a charm!

I also did everything before...uninstalling node, and so. But just deleting ionic.config was the solution. Keep in mind that the file is in your home folder, not in the folder where you have your app.

As the problem appeared suddenly, I was not convinced by the config_file solution, as I didn't modified anything before the error. So I was thinking more in some corrupted file problem, and @seokochin solution was more logical in that case.

Thanks!

Thanks @seokochin This worked for me as well

[zeeshananjumjunaidi]

Comments were causing problem for me. it needs to be pure simple json structure like following:

{
  "name": "ionic3-sample",
  "app_id": "",
  "type": "ionic-angular",
  "integrations": {
    "cordova": {}
  },
  "proxies": [
    { 
      "path": "/JSON",
      "proxyUrl": "http://192.168.1.123/JSON"
    }
  ]
}

thanks a lot @seokochin you save my time a lot..

[HeshamEG]

the easy way just delete file config.json located in C:.ionic\config.json then ionic serve again and solved 🍡

Goto this path- C:/Users/{username}/.ionic find file (ionic.config) and delete that file.
