Ionic JSON parse exception

Ionic Framework ionic-v3
1

My PC recently crashed while halfway through building my Ionic 2 project, and now I can’t run any ionic commands. When I try to run any ionic command in any of my ionic projects I get the following command output:

 SyntaxError: Unexpected token   in JSON at position 0
    at Object.parse (native)

I’ve tried removing all the node_modules in my project and reinstalling them as well as uninstalling and reinstalling both cordova and ionic. I’ve also cleared the contents of my www folder. I’ve removed and re-added my platforms using cordova commands, since ionic doesn’t work.

I can’t run ionic info to get my version info.

Any suggestion on what else I can do to get ionic working again?

Maybe, after reinstalling everything, did you check if your package.json was correct regarding the updated libs?

See

Ionic 2 RC.2:

App-Script 0.0.42:

http://blog.ionic.io/improvements-to-ionic-build-process/

If no, try to update package.json, delete and reinstall node_modules

Bug just a suggestion

My dependencies and app-scripts are up to date. This is definitely a global ionic issue. I can’t run any ionic commands in any directory.

I’m thinking there’s some global ionic cli cache somewhere that I need to clear.

sorry to hear and sorry for not having any other ideas right now

I have now also gone so far as to uninstall node, delete npm and npm-cache directories, run ccleaner to clean temp files, reboot, reinstall node, reinstall ionic and cordova.

I’ve found the source of the problem! My C:/Users/{username}/.ionic/ionic.config file was corrupted when my pc crashed.

Weird that that file NEVER gets cleared when uninstalling ionic.

Can anyone please post me the contents of theirs so I can see what to put in there?

EDIT: Nevermind, the file was filled the proper JSON object.

So, the first error was definitely because the file was not valid JSON. Perhaps the crash caused that corruption :frowning:

Were you able to get passed this error? Double check the file and make sure it really is valid (no dangling commas, etc.)
