Hi, thanks for the reply. I believe it’s correct, but can’t test since the problem is solved.

Someone told me to reinstall everything, may be a npm bug. So, I did and now using NodeJS v6.7.0.
I think there’s nothing to do with the version, but with some corrupted package.
After uninstall, excluded all npm folders on %appdata% and now works fine


[EDIT/UPDATE] i ran npm install (again) as well as opted out of the cordova telemetry (kept seeing those messages) and now i don’t see the tslint issue anymore. I’m on to a new issue, but probably unrelated.

I’m running into this same thing. Tried Updating to node v6, tried uninstalling and reinstalling, but I’m still getting the same tslint error. Can you point to the directions you followed (or describe them) for uninstalling/reinstalling (maybe I’m missing something)


Go to %appdata% and delete folders nodejs and npm, after uninstall.
After, install again.

I am have same issue
its windows 8,
node v4.6.0 npm
npm 2.15.9

tried uninstall and reinstall
tried deleting %appdata%
tried uninstall everything and then reinstall
but still getting
